CVE-2025-27773 1 Simplesamlphp 1 Saml2 2026-04-15 8.6 High
The SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. Prior to versions 4.17.0 and 5.0.0-alpha.20, there is a signature confusion attack in the HTTPRedirect binding. An attacker with any signed SAMLResponse via the HTTP-Redirect binding can cause the application to accept an unsigned message. Versions 4.17.0 and 5.0.0-alpha.20 contain a fix for the issue.
CVE-2025-55278 1 Hcltech 1 Devops Loop 2026-04-15 8.1 High
Improper authentication in the API authentication middleware of HCL DevOps Loop allows authentication tokens to be accepted without proper validation of their expiration and cryptographic signature. As a result, an attacker could potentially use expired or tampered tokens to gain unauthorized access to sensitive resources and perform actions with elevated privileges.
CVE-2024-36277 2026-04-15 5.3 Medium
Improper verification of cryptographic signature issue exists in "FreeFrom - the nostr client" App versions prior to 1.3.5 for Android and iOS. The affected app cannot detect event data with invalid signatures.
CVE-2024-7479 1 Teamviewer 2 Full Client, Host 2026-04-15 8.8 High
Improper verification of cryptographic signature during installation of a VPN driver via the TeamViewer_service.exe component of TeamViewer Remote Clients prior version 15.58.4 for Windows allows an attacker with local unprivileged access on a Windows system to elevate their privileges and install drivers.
CVE-2024-45341 1 Redhat 1 Enterprise Linux 2026-04-15 6.1 Medium
A certificate with a URI which has a IPv6 address with a zone ID may incorrectly satisfy a URI name constraint that applies to the certificate chain. Certificates containing URIs are not permitted in the web PKI, so this only affects users of private PKIs which make use of URIs.
CVE-2025-40758 1 Mendix 2 Mendix, Saml 2026-04-15 8.7 High
A vulnerability has been identified in Mendix SAML (Mendix 10.12 compatible) (All versions < V4.0.3), Mendix SAML (Mendix 10.21 compatible) (All versions < V4.1.2), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.21). Affected versions of the module insufficiently enforce signature validation and binding checks. This could allow unauthenticated remote attackers to hijack an account in specific SSO configurations.
CVE-2025-68113 1 Altcha 1 Altcha 2026-04-15 6.5 Medium
ALTCHA is privacy-first software for captcha and bot protection. A cryptographic semantic binding flaw in ALTCHA libraries allows challenge payload splicing, which may enable replay attacks. The HMAC signature does not unambiguously bind challenge parameters to the nonce, allowing an attacker to reinterpret a valid proof-of-work submission with a modified expiration value. This may allow previously solved challenges to be reused beyond their intended lifetime, depending on server-side replay handling and deployment assumptions. The vulnerability primarily impacts abuse-prevention mechanisms such as rate limiting and bot mitigation. It does not directly affect data confidentiality or integrity. This issue has been addressed by enforcing explicit semantic separation between challenge parameters and the nonce during HMAC computation. Users are advised to upgrade to patched versions, which include version 1.0.0 of the altcha Golang package, version 1.0.0 of the altcha Rubygem, version 1.0.0 of the altcha pip package, version 1.0.0 of the altcha Erlang package, version 1.4.1 of the altcha-lib npm package, version 1.3.1 of the altcha-org/altcha Composer package, and version 1.3.0 of the org.altcha:altcha Maven package. As a mitigation, implementations may append a delimiter to the end of the `salt` value prior to HMAC computation (for example, `<salt>?expires=<time>&`). This prevents ambiguity between parameters and the nonce and is backward-compatible with existing implementations, as the delimiter is treated as a standard URL parameter separator.
CVE-2025-52556 2026-04-15 N/A
rfc3161-client is a Python library implementing the Time-Stamp Protocol (TSP) described in RFC 3161. Prior to version 1.0.3, there is a flaw in the timestamp response signature verification logic. In particular, chain verification is performed against the TSR's embedded certificates up to the trusted root(s), but fails to verify the TSR's own signature against the timestamping leaf certificates. Consequently, vulnerable versions perform insufficient signature validation to properly consider a TSR verified, as the attacker can introduce any TSR signature so long as the embedded leaf chains up to some root TSA. This issue has been patched in version 1.0.3. There is no workaround for this issue.
CVE-2024-47943 2026-04-15 9.8 Critical
The firmware upgrade function in the admin web interface of the RittalĀ IoT Interface & CMC III Processing Unit devices checks if the patch files are signed before executing the containing run.sh script. The signing process is kind of an HMAC with a long string as key which is hard-coded in the firmware and is freely available for download. This allows crafting malicious "signed" .patch files in order to compromise the device and execute arbitrary code.
CVE-2026-33895 1 Digitalbazaar 1 Forge 2026-04-14 7.5 High
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order (`S >= L`). A valid signature and its `S + L` variant both verify in forge, while Node.js `crypto.verify` (OpenSSL-backed) rejects the `S + L` variant, as defined by the specification. This class of signature malleability has been exploited in practice to bypass authentication and authorization logic (see CVE-2026-25793, CVE-2022-35961). Applications relying on signature uniqueness (i.e., dedup by signature bytes, replay tracking, signed-object canonicalization checks) may be bypassed. Version 1.4.0 patches the issue.
CVE-2026-32883 2 Botan Project, Randombit 2 Botan, Botan 2026-04-14 5.9 Medium
Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0.
CVE-2026-34840 2 Hackerbay, Oneuptime 2 Oneuptime, Oneuptime 2026-04-14 8.1 High
OneUptime is an open-source monitoring and observability platform. Prior to version 10.0.42, OneUptime's SAML SSO implementation (App/FeatureSet/Identity/Utils/SSO.ts) has decoupled signature verification and identity extraction. isSignatureValid() verifies the first <Signature> element in the XML DOM using xml-crypto, while getEmail() always reads from assertion[0] via xml2js. An attacker can prepend an unsigned assertion containing an arbitrary identity before a legitimately signed assertion, resulting in authentication bypass. This issue has been patched in version 10.0.42.
CVE-2026-0234 1 Palo Alto Networks 2 Cortex Xsiam Microsoft Teams Marketplace, Cortex Xsoar Microsoft Teams Marketplace 2026-04-14 N/A
An improper verification of cryptographic signature vulnerability exists in Cortex XSOAR and Cortex XSIAM platforms during integration of Microsoft Teams that enables an unauthenticated user to access and modify protected resources.
CVE-2026-32294 1 Jetkvm 2 Jetkvm, Kvm 2026-04-10 4.7 Medium
JetKVM prior to 0.5.4 does not verify the authenticity of downloaded firmware files. An attacker-in-the-middle or a compromised update server could modify the firmware and the corresponding SHA256 hash to pass verification.
CVE-2026-21002 1 Samsung 1 Galaxy Store 2026-04-09 5.5 Medium
Improper verification of cryptographic signature in Galaxy Store prior to version 4.6.03.8 allows local attacker to install arbitrary application.
CVE-2017-13083 1 Akeo 1 Rufus 2026-04-07 N/A
Akeo Consulting Rufus prior to version 2.17.1187 does not adequately validate the integrity of updates downloaded over HTTP, allowing an attacker to easily convince a user to execute arbitrary code
CVE-2026-34377 2 Zcashfoundation, Zfnd 4 Zebra, Zebra-consensus, Zebra and 1 more 2026-04-07 8.1 High
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.0 and zebra-consensus version 5.0.1, a logic error in Zebra's transaction verification cache could allow a malicious miner to induce a consensus split. By matching a valid transaction's txid while providing invalid authorization data, a miner could cause vulnerable Zebra nodes to accept an invalid block, leading to a consensus split from the rest of the Zcash network. This would not allow invalid transactions to be accepted but could result in a consensus split between vulnerable Zebra nodes and invulnerable Zebra and Zcashd nodes. This issue has been patched in zebrad version 4.3.0 and zebra-consensus version 5.0.1.
CVE-2026-34240 1 Appsup-dart 1 Jose 2026-04-07 7.5 High
JOSE is a Javascript Object Signing and Encryption (JOSE) library. Prior to version 0.3.5+1, a vulnerability in jose could allow an unauthenticated, remote attacker to forge valid JWS/JWT tokens by using a key embedded in the JOSE header (jwk). The vulnerability exists because key selection could treat header-provided jwk as a verification candidate even when that key was not present in the trusted key store. Since JOSE headers are untrusted input, an attacker could exploit this by creating a token payload, embedding an attacker-controlled public key in the header, and signing with the matching private key. Applications using affected versions for token verification are impacted. This issue has been patched in version 0.3.5+1. A workaround for this issue involves rejecting tokens where header jwk is present unless that jwk matches a key already present in the application's trusted key store.
CVE-2026-34872 2 Arm, Mbed-tls 3 Mbed Tls, Tf-psa-crypto, Mbedtls 2026-04-07 9.1 Critical
An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values (lack of contributory behavior). This is a problem for protocols that depend on contributory behavior (which is not the case for TLS). The attack can be carried by the peer, or depending on the protocol by an active network attacker (person in the middle).
CVE-2026-34155 2 Pengutronix, Rauc 2 Rauc, Rauc 2026-04-03 5.3 Medium
RAUC controls the update process on embedded Linux systems. Prior to version 1.15.2, RAUC bundles using the 'plain' format exceeding a payload size of 2 GiB cause an integer overflow which results in a signature which covers only the first few bytes of the payload. Given such a bundle with a legitimate signature, an attacker can modify the part of the payload which is not covered by the signature. This issue has been patched in version 1.15.2.
