Openclaw: >> Openclaw Security Vulnerabilities
OpenClaw versions prior to 2026.2.15 contain a denial of service vulnerability in the web_fetch tool that allows attackers to crash the Gateway process through memory exhaustion by parsing oversized or deeply nested HTML responses. Remote attackers can social-engineer users into fetching malicious URLs with pathological HTML structures to exhaust server memory and cause service unavailability.

In OpenClaw before 2026.2.23, tools.exec.safeBins validation for sort could be bypassed via GNU long-option abbreviations (such as --compress-prog) in allowlist mode, leading to approval-free execution paths that were intended to require approval. Only an exact string such as --compress-program was denied.

OpenClaw is a personal AI assistant. In versions 2026.2.13 and below, when using macOS, the Claude CLI keychain credential refresh path constructed a shell command to write the updated JSON blob into Keychain via security add-generic-password -w .... Because OAuth tokens are user-controlled data, this created an OS command injection risk. This issue has been fixed in version 2026.2.14.

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, Cron webhook delivery in src/gateway/server-cron.ts uses fetch() directly, so webhook targets can reach private/metadata/internal endpoints without SSRF policy checks. This issue was fixed in version 2026.2.19.

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, the ACP bridge accepts very large prompt text blocks and can assemble oversized prompt payloads before forwarding them to chat.send. Because ACP runs over local stdio, this mainly affects local ACP clients (for example IDE integrations) that send unusually large inputs. This issue has been fixed in version 2026.2.19.

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, the Discord moderation action handling (timeout, kick, ban) uses sender identity from request parameters in tool-driven flows, instead of trusted runtime sender context. In setups where Discord moderation actions are enabled and the bot has the necessary guild permissions, a non-admin user can request moderation actions by spoofing sender identity fields. This issue has been fixed in version 2026.2.18.

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, skills/skill-creator/scripts/package_skill.py (a local helper script used when authors package skills) previously followed symlinks while building .skill archives. If an author runs this script on a crafted local skill directory containing symlinks to files outside the skill root, the resulting archive can include unintended file contents. If exploited, this vulnerability can lead to potential unintentional disclosure of local files from the packaging machine into a generated .skill artifact, but requires local execution of the packaging script on attacker-controlled skill contents. This issue has been fixed in version 2026.2.18.

OpenClaw is a personal AI assistant. In versions 2026.2.13 and below of the OpenClaw CLI, the process cleanup uses system-wide process enumeration and pattern matching to terminate processes without verifying if they are owned by the current OpenClaw process. On shared hosts, unrelated processes can be terminated if they match the pattern. The CLI runner cleanup helpers can kill processes matched by command-line patterns without validating process ownership. This issue has been fixed in version 2026.2.14.

OpenClaw is a personal AI assistant. Prior to version 2026.2.15, in some shared-agent deployments, OpenClaw session tools (`sessions_list`, `sessions_history`, `sessions_send`) allowed broader session targeting than some operators intended. This is primarily a configuration/visibility-scoping issue in multi-user environments where peers are not equally trusted. In Telegram webhook mode, monitor startup also did not fall back to per-account `webhookSecret` when only the account-level secret was configured. In shared-agent, multi-user, less-trusted environments: session-tool access could expose transcript content across peer sessions. In single-agent or trusted environments, practical impact is limited. In Telegram webhook mode, account-level secret wiring could be missed unless an explicit monitor webhook secret override was provided. Version 2026.2.15 fixes the issue.

OpenClaw is a personal AI assistant. Prior to version 2026.2.15, `normalizeForHash` in `src/agents/sandbox/config-hash.ts` recursively sorted arrays that contained only primitive values. This made order-sensitive sandbox configuration arrays hash to the same value even when order changed. In OpenClaw sandbox flows, this hash is used to decide whether existing sandbox containers should be recreated. As a result, order-only config changes (for example Docker `dns` and `binds` array order) could be treated as unchanged and stale containers could be reused. This is a configuration integrity issue affecting sandbox recreation behavior. Starting in version 2026.2.15, array ordering is preserved during hash normalization; only object key ordering remains normalized for deterministic hashing.
