OpenClaw before 2026.3.22 contains an incomplete host environment variable sanitization vulnerability in host-env-security-policy.json and host-env-security.ts that allows package-manager environment overrides. Attackers can exploit approved exec requests to redirect package resolution or runtime bootstrap to attacker-controlled infrastructure and execute trojanized content.

OpenClaw before 2026.3.31 fails to properly sanitize PIP_INDEX_URL and UV_INDEX_URL environment variables in host execution contexts, allowing attackers to redirect Python package-index traffic. Attackers can exploit this bypass to intercept or manipulate package management operations by injecting malicious index URLs through unsanitized environment variables.

OpenClaw before 2026.4.8 treats shared reply MEDIA paths as trusted, allowing crafted references to trigger cross-channel local file exfiltration. Attackers can exploit this by crafting malicious shared reply MEDIA references to cause another channel to read local file paths as trusted generated media.

Sandbox escape due to incorrect boundary conditions in the WebRTC: Networking component. This vulnerability was fixed in Firefox ESR 140.10.1.

A vulnerability was determined in Artifex MuPDF up to 1.28.0. The impacted element is the function fz_subset_cff_for_gids of the file subset-cff.c of the component CFF Index Handler. This manipulation causes out-of-bounds read. The attack can only be executed locally. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through a bug report but has not responded yet.

OpenClaw before 2026.3.31 contains an incomplete host-env-security-policy.json that fails to restrict compiler binary environment variables, allowing untrusted models to substitute CC, CXX, CARGO_BUILD_RUSTC, and CMAKE_C_COMPILER via environment overrides. Attackers with approved host-exec requests can override compiler binaries to execute arbitrary code during build processes.

Information disclosure due to incorrect boundary conditions in the Audio/Video component. This vulnerability was fixed in Firefox 150.0.1, Firefox ESR 140.10.1, and Firefox ESR 115.35.1.

OpenClaw before 2026.3.31 stores Nostr privateKey as plaintext in configuration, allowing exposure through config.get method calls that bypass redaction mechanisms. Attackers can retrieve unredacted configuration data to obtain plaintext signing keys used for Nostr protocol operations.

Inappropriate implementation in Tint in Google Chrome prior to 147.0.7727.138 allowed a remote attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)

OpenClaw before 2026.4.8 contains improper input validation in base64 decode paths that allocate memory before enforcing decoded-size limits. Attackers can exploit multiple code paths to cause memory exhaustion or denial of service through crafted base64-encoded input.
