Webhook secret brute-forcing in OpenClaw before 2026.3.12 enables attackers to forge authenticated webhooks by exploiting pre-authentication rate limit bypass. Unauthenticated remote attackers can systematically guess webhook secrets without triggering rate limiting (which only applies post-authentication), then submit forged webhook payloads to compromise system integrity and confidentiality. CVSS 9.8 (Critical) with network attack vector and no authentication required. No public exploit identified at time of analysis, though exploitation requires only standard HTTP tooling. EPSS data not available; exploitation appears automatable given the straightforward nature of brute-force attacks against webhook endpoints.

Sandbox escape in OpenClaw (before version 2026.3.11) allows local authenticated users to write arbitrary files outside validated directories via a TOCTOU race condition during staged file writes. The fs-bridge component fails to anchor temporary file operations to verified parent directories, enabling attackers to manipulate path aliases between validation and execution phases. CVSS 7.5 (High) reflects the local attack vector with high complexity, but scope change (S:C) indicates potential container/sandbox breakout. No public exploit identified at time of analysis, though the race condition vulnerability class (CWE-367) is well-understood by attackers.

OpenClaw before 2026.3.11 allows authenticated local attackers to bypass sandbox boundaries and write files outside validated paths via a time-of-check-time-of-use race condition in the fs-bridge writeFile commit operation. An attacker with local access and sufficient privileges can exploit unanchored container paths during file move operations to redirect committed files outside the sandbox, achieving arbitrary file write capabilities within the container mount namespace. No public exploit code or active exploitation has been confirmed.

OpenClaw before version 2026.3.11 allows local authenticated users to bypass local authentication boundaries through a credential fallback vulnerability where unavailable local gateway.auth.token and gateway.auth.password SecretRefs are incorrectly treated as unset, enabling fallback to remote credentials in local-only mode. The vulnerability requires local access and specific misconfiguration of auth references but can result in information disclosure if an attacker selects incorrect credential sources via CLI and helper paths. No public exploit code or active exploitation has been identified.

OpenClaw before 2026.3.8 allows authenticated remote attackers to bypass approval controls in the system.run function by obtaining approval for a script, modifying the approved script file before execution, and executing malicious content while preserving the approved command structure. This approval-execution window vulnerability enables privilege escalation and code execution with low complexity and no user interaction required. No public exploit code or active exploitation has been confirmed at the time of analysis.

Unauthenticated attackers can modify WooPayments plugin settings through a missing capability check in the 'save_upe_appearance_ajax' AJAX function, affecting all versions up to and including 10.5.1. This allows remote attackers to alter payment appearance configurations without authentication, potentially disrupting payment processing or customer experience. No public exploit code or active exploitation has been identified at time of analysis.

Unauthenticated attackers can directly access view PHP files in the Truebooker WordPress plugin (versions up to 1.1.4) to disclose sensitive information, such as user data or system configuration details exposed in those templates. The vulnerability requires only network access and no authentication, making it trivially exploitable via simple HTTP requests to exposed PHP files. No public exploit code or active exploitation has been confirmed at this time.

baserCMS versions prior to 5.2.3 allow unauthenticated remote attackers to bypass administrative form submission controls via a public mail API, enabling arbitrary form submissions even when the form is configured to reject new entries. This authentication bypass has a CVSS score of 5.3 and permits attackers to inject spam or abuse content without authorization, circumventing intended intake restrictions. Vendor-released patch available in version 5.2.3.

SourceCodester Loan Management System v1.0 allows authenticated administrators to create loan plans with negative interest rates by submitting negative values in HTTP POST requests, bypassing client-side validation that lacks server-side enforcement. This business logic vulnerability enables attackers with administrative credentials to manipulate loan terms and potentially cause financial harm to the organization. Publicly available exploit code exists demonstrating the attack.

Node.js Permission Model bypass in FileHandle.chmod() and FileHandle.chown() promise-based methods allows local authenticated users with restricted --allow-fs-write to modify file permissions and ownership on already-open file descriptors, circumventing intended write restrictions. The vulnerability affects Node.js 20.x, 22.x, 24.x, and 25.x when running under the --permission flag; the callback-based equivalents (fs.fchmod, fs.fchown) were correctly patched in CVE-2024-36137, but the promises API was incompletely fixed. CVSS 3.3 with low real-world impact due to local-only attack vector and requirement for pre-existing file access.

Unix Domain Socket operations in Node.js 25.x bypass permission model enforcement, allowing local processes to create IPC endpoints and communicate with other processes when run with --permission flag but without --allow-net. An authenticated local attacker can establish inter-process communication channels that circumvent the intended network isolation boundary, resulting in information disclosure and potential privilege escalation within the same host. No public exploit code identified at time of analysis, though the vulnerability affects an experimental permission enforcement feature.

Parse Server's GraphQL API endpoint bypasses the configured allowOrigin CORS restriction, allowing cross-origin requests from any website while the REST API correctly enforces the policy. This authentication bypass affects Parse Server instances where operators have configured origin restrictions to limit API access, enabling attackers from arbitrary websites to interact with the GraphQL endpoint without respecting these security controls. The vulnerability has been patched in Parse Server 8 and 9 via upstream fixes, and no public exploit code or active exploitation has been confirmed.
