CVE-2025-71402 1 Better-auth 1 Better-auth\/oauth-provider 2026-08-03 N/A
better-auth versions greater than 1.3.34 and before 1.4.0 contain a vulnerability in the multi-session plugin's /sign-out after-hook, which trusts raw multi-session cookies and forwards extracted values to internalAdapter.deleteSessions without verifying the cookie signature (e.g., via getSignedCookie). An attacker can supply a forged _multi-* cookie to trigger deletion of arbitrary session tokens.
CVE-2026-55735 1 Ueberauth 1 Guardian 2026-08-03 N/A
Improper Verification of Cryptographic Signature in ueberauth guardian allows an unauthenticated attacker to revoke a victim's session with a forged token. Guardian.revoke/3 in lib/guardian.ex decodes the supplied token with peek/1, which performs no signature verification (it only base64-decodes the JWT header and payload). The resulting unverified claims are forwarded directly to the configured token module's revoke callback and the implementation's on_revoke callback, a state-mutating sink. The sibling operations refresh/2 and exchange/4 both call decode_and_verify first, so the signature is checked before anything acts on the claims; revoke/3 is the only state-mutating path that acts on claims without verifying the signature. An attacker who knows or guesses a victim's identifying claim values (jti, sub) can forge a JWT carrying those claims, sign it with an arbitrary key, and submit it to any endpoint that funnels a caller-supplied token into Guardian.revoke/3 (the standard logout / session-revocation pattern). When the token module mutates state keyed by the claims (whitelist deletion or blacklist insertion, for example a GuardianDb-style store), the victim's legitimate session is evicted. This is an unauthenticated session-revocation denial of service; the attacker never needs the signing secret. This issue affects guardian: from 1.0.0 before 2.4.1.
CVE-2026-59643 1 Legion Of The Bouncy Castle Inc. 2 Bc-fja, Bc-java 2026-08-03 N/A
In Bouncy Castle for Java before 1.85, OpenPGP inline-signature policy failures silently ignored. This issue also affects Bouncy Castle for Java FIPS (BC-FJA) before bcpg-fips 2.0.13.
CVE-2026-59639 1 Legion Of The Bouncy Castle Inc. 3 Bc-fja, Bc-java, Bc-lts-java 2026-08-03 N/A
In Bouncy Castle for Java before 1.85, CMS verifySignatures returns true for SignedData with zero signers. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bcpkix-fips 1.0.12 (1.0.X series), 2.0.12 (2.0.X series) and 2.1.12 (2.1.X series).
CVE-2026-12860 1 Legion Of The Bouncy Castle Inc. 2 Bc-java, Bc-lts-java 2026-08-03 N/A
In Bouncy Castle for Java before 1.85, RSA PKCS#1 verification skips last two hash bytes in NULL-omitted path. This issue also affects Bouncy Castle for Java LTS before 2.73.12.
CVE-2026-53501 1 Thumbor 1 Thumbor 2026-08-02 8.2 High
Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, Thumbor’s HMAC validation can be bypassed due to the use of Python’s .replace() when removing the signature from the URL before validation. Since .replace() removes all occurrences of the substring, an attacker can insert the same signature multiple times in the URL and manipulate the final URL used for validation. This allows crafting URLs where the validated string differs from the actual requested resource, enabling loading images from unintended domains or paths. This issue is fixed in 7.8.0.
CVE-2026-54787 2 Redhat, Sigstore 2 Hummingbird, Sigstore-go 2026-08-02 3.1 Low
sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.1, sigstore-go does not check a bundle signing timestamp against the validity window of an ExpiringKey wrapping a self-managed long-lived signing key without a certificate, which can allow an attacker holding expired key material to sign accepted bundles. This issue is fixed in version 1.2.1.
CVE-2026-56451 2026-07-31 10 Critical
A vulnerability has been identified in Opcenter X (All versions < V2604). Affected applications do not properly validate the algorithm specified in the JSON Web Token (JWT) header. This could allow an unauthenticated remote attacker to forge arbitrary JWT, bypass authentication mechanisms and impersonate any user including administrative accounts, potentially gaining full unauthorized access to the application.
CVE-2026-48815 1 Sigstore 1 Sigstore 2026-07-30 7.5 High
sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the documented certificateOIDs option in sigstore.verify() is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked and applications relying on certificateOIDs to restrict which certificates may sign artifacts can accept unauthorized certificates. This issue is fixed in version 4.1.1.
CVE-2026-48758 1 Sigstore 1 Sigstore 2026-07-30 5.4 Medium
sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.2.1, the preAuthEncoding function in @sigstore/core uses Node.js ascii encoding when converting the PAE string to bytes, allowing payloadType to be mutated after signing without invalidating the signature and breaking the type-binding guarantee that DSSE is designed to provide. This issue is fixed in version 3.2.1.
CVE-2026-45795 1 Jansson Project 1 Jansson 2026-07-30 5.3 Medium
The Janssen Project is an open-source identity and access management (IAM) platform. Prior to 2.0.0, jans-auth-server accepts unsigned JWE request objects because JwtAuthorizationRequest skips inner signature validation when jwe.getSignedJWTPayload() returns null, and AuthzRequestService.processRequestObject() does not reject the unrecognized RSA-OAEP algorithm when forceSignedRequestObject=true. This issue is fixed in version 2.0.0.
CVE-2026-17872 1 Google 1 Chrome 2026-07-30 6.1 Medium
Cryptographic Flaw in WebAppInstalls in Google Chrome on Android prior to 151.0.7922.72 allowed a local attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-13305 1 Autel 1 Maxicharger Ac Elite Home 2026-07-30 N/A
Autel MaxiCharger AC Elite Home Software Update Improper Verification of Cryptographic Signature Arbitrary Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of software updates. The issue results from the lack of proper validation of a user-supplied software update image. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29062.
CVE-2026-17666 1 Google 1 Chrome 2026-07-30 9.1 Critical
Cryptographic Flaw in Enterprise in Google Chrome prior to 151.0.7922.72 allowed an attacker in a privileged network position to bypass discretionary access control via malicious network traffic. (Chromium security severity: High)
CVE-2026-44104 2 Phoenix Contact, Phoenixcontact 8 Charx Sec 3000, Charx Sec 3050, Charx Sec 3100 and 5 more 2026-07-30 9.8 Critical
The firmware update process for the basemodule of the charging controller only validates the CRC32 checksum without cryptographic signature verification. This allows an unauthenticated remote attacker to install a modified firmware, resulting in full system compromise.
CVE-2026-59243 1 Apache 1 Airflow Fab Provider 2026-07-29 9.8 Critical
The FAB auth manager's Azure AD OAuth login defaulted `verify_signature=False` when decoding the ID token, so an attacker able to present a forged or unsigned (`alg:none`) ID token to the OAuth callback could bypass authentication and log in as an arbitrary user, including one holding the Admin role (CWE-347). Deployments running the FAB auth manager with the Azure AD OAuth login path under its default configuration are affected; the Authentik path already defaulted to `True`. This issue affects `apache-airflow-providers-fab` before 3.7.3. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.3, which defaults `verify_signature=True`.
CVE-2026-63237 1 Three Learning 1 Koollab Lms 2026-07-29 4.8 Medium
A TOTP two-factor authentication bypass vulnerability in Koollab LMS allowed an attacker to supply a client-controlled seed to generate a matching one-time password and bypass the second authentication factor, potentially enabling unauthorised access to administrator accounts.
CVE-2026-49834 1 Sigstore 1 Sigstore-go 2026-07-28 5.9 Medium
sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.0, a verifier configured with WithTransparencyLog(N>1) or WithSignedCertificateTimestamps(N>1) counts verified witnesses per entry or per validation path rather than per log authority, allowing a single compromised transparency log or CT log to satisfy multi-log threshold requirements and defeat the multi-log policy. This issue is fixed in version 1.2.0.
CVE-2026-4258 1 Bitwiseshiftleft 2 Sjcl, Stanford Javascript Crypto Library 2026-07-28 7.5 High
Versions of the package sjcl before 1.0.9 are vulnerable to Improper Verification of Cryptographic Signature due to missing point-on-curve validation in sjcl.ecc.basicKey.publicKey(). An attacker can recover a victim's ECDH private key by sending crafted off-curve public keys and observing ECDH outputs. The dhJavaEc() function directly returns the raw x-coordinate of the scalar multiplication result (no hashing), providing a plaintext oracle without requiring any decryption feedback.
CVE-2026-65616 1 Jfrog 1 Artifactory 2026-07-28 8.8 High
Incorrect authorization validation in refresh token signature allows non-admin users to obtain a signed JFrog administrator token.
