CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: publish jinode after initialization
ext4_inode_attach_jinode() publishes ei->jinode to concurrent users.
It used to set ei->jinode before jbd2_journal_init_jbd_inode(),
allowing a reader to observe a non-NULL jinode with i_vfs_inode
still unset.
The fast commit flush path can then pass this jinode to
jbd2_wait_inode_data(), which dereferences i_vfs_inode->i_mapping and
may crash.
Below is the crash I observe:
```

Fix this by initializing the jbd2_inode first.
Use smp_wmb() and WRITE_ONCE() to publish ei->jinode after
initialization. Readers use READ_ONCE() to fetch the pointer. |
| OpenClaw before 2026.4.22 derives loopback MCP owner context from spoofable server-issued bearer tokens in request headers. Non-owner loopback clients can present themselves as owner to bypass owner-gated operations by manipulating the sender-owner header metadata. |
| OpenClaw before 2026.4.20 contains a server-side request forgery vulnerability in QQBot direct media upload that skips URL validation. Attackers can bypass SSRF protections by sending crafted image URLs to uploadC2CMedia and uploadGroupMedia endpoints to relay unintended requests. |
| OpenClaw before 2026.4.22 contains a server-side request forgery vulnerability in the Zalo plugin's sendPhoto function that fails to validate outbound photo URLs through the SSRF guard. Attackers can bypass SSRF protection by providing malicious photo URLs to the Zalo Bot API, enabling unauthorized access to internal resources. |
| OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime. |
| OpenClaw before 2026.4.20 fails to properly reserve the OPENCLAW_ runtime-control environment namespace in workspace dotenv files, allowing attackers to override critical runtime variables. Malicious workspaces can set variables like OPENCLAW_GIT_DIR to manipulate trusted OpenClaw runtime behavior during source-update or installer flows. |
| OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in the OpenShell filesystem bridge that allows attackers to read files outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and access unauthorized file contents. |
| OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in OpenShell sandbox filesystem writes that allows attackers to redirect writes outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and write files outside the local mount root. |
| OpenClaw before 2026.4.15 contains an arbitrary file read vulnerability in the QMD backend memory_get function that allows callers to read any Markdown files within the workspace root. Attackers with access to the memory tool can bypass path restrictions by providing arbitrary workspace Markdown paths to read files outside canonical memory locations or indexed QMD result sets. |
| OpenClaw before 2026.4.15 contains an authorization bypass vulnerability in Matrix room control-command authorization that trusts DM pairing-store entries. Attackers with DM-paired sender IDs can execute room control commands without being in configured allowlists by posting in bot rooms, potentially enabling privileged OpenClaw behavior. |
| OpenClaw before 2026.4.15 contains an authentication bypass vulnerability in Feishu webhook and card-action validation that allows unauthenticated requests to reach command dispatch. Missing encryptKey configuration and blank callback tokens fail open instead of rejecting requests, enabling attackers to bypass signature verification and replay protection to execute arbitrary commands. |
| OpenClaw before 2026.4.15 captures resolved bearer-auth configuration at startup, allowing revoked tokens to remain valid after SecretRef rotation. Gateway HTTP and WebSocket handlers fail to re-resolve authentication per-request, enabling attackers to use rotated-out bearer tokens for unauthorized gateway access. |
| OpenClaw before 2026.4.10 contains an insufficient environment variable denylist vulnerability in its exec environment policy that allows operator-supplied overrides of high-risk interpreter startup variables including VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES. Attackers can exploit this by manipulating these environment variables to influence downstream execution behavior or network connectivity. |
| OpenClaw versions 2026.4.10 before 2026.4.14 fail to persist session context during delivery queue recovery for media replay. Attackers can exploit recovered queued outbound media to bypass group tool policy enforcement and weaken channel media restrictions after service restart or recovery. |
| OpenClaw before 2026.4.10 contains a server-side request forgery vulnerability in browser navigation policy that allows attackers to bypass hostname validation through DNS rebinding attacks. Attackers can exploit inconsistent hostname resolution between validation and actual network requests to pivot to internal resources via unallowlisted hostname URLs. |
| OpenClaw before 2026.4.10 contains an improper network binding vulnerability in the sandbox browser CDP relay that exposes Chrome DevTools Protocol on 0.0.0.0. Attackers can access the DevTools protocol outside intended local sandbox boundaries by exploiting the overly broad binding configuration. |
| OpenClaw before 2026.4.10 contains an incomplete navigation guard vulnerability that allows attackers to trigger navigation without complete SSRF policy enforcement. Browser press/type style interactions, including pressKey and type submit flows, can bypass post-action security checks to execute unauthorized navigation. |
| OpenClaw before 2026.4.10 contains an insufficient access control vulnerability in Nostr plugin HTTP profile routes that allows operators with write permissions to persist profile configuration without requiring admin authority. Attackers with operator.write scope can modify Nostr profile settings through unprotected mutation endpoints to gain unauthorized configuration persistence. |
| OpenClaw versions 2026.3.31 before 2026.4.10 contain a privilege escalation vulnerability where heartbeat owner downgrade detection misses local background async exec completion events. Attackers can exploit this by providing untrusted completion content to leave a run in a more privileged context than intended. |
| OpenClaw before 2026.4.9 contains a file read vulnerability allowing attackers to bypass navigation guards through browser act/evaluate interactions. Attackers can pivot into the local CDP origin and create or read disallowed file:// pages despite direct navigation policy restrictions. |
