CVE-2026-22217 WRITEUP MEDIUM WRITEUP
OpenClaw 2026.2.22 < 2026.2.23 - Arbitrary Binary Execution via $SHELL Environment Variable Trusted Prefix Fallback
OpenClaw version 2026.2.22 prior to 2026.2.23 contains an arbitrary code execution vulnerability in shell-env that allows attackers to execute attacker-controlled binaries by exploiting trusted-prefix fallback logic for the $SHELL variable. An attacker can influence the $SHELL environment variable on systems with writable trusted-prefix directories such as /opt/homebrew/bin to execute arbitrary binaries in the OpenClaw process context.
CVSS 6.1
CVE-2026-27522 WRITEUP MEDIUM WRITEUP
OpenClaw < 2026.2.24 - Arbitrary File Read via sendAttachment and setGroupIcon Message Actions
OpenClaw versions prior to 2026.2.24 contain a local media root bypass vulnerability in sendAttachment and setGroupIcon message actions when sandboxRoot is unset. Attackers can hydrate media from local absolute paths to read arbitrary host files accessible by the runtime user.
CVSS 6.5
CVE-2026-27523 WRITEUP MEDIUM WRITEUP
OpenClaw < 2026.2.24 - Sandbox Bind Validation Bypass via Symlink-Parent Missing-Leaf Paths
OpenClaw versions prior to 2026.2.24 contain a sandbox bind validation vulnerability allowing attackers to bypass allowed-root and blocked-path checks via symlinked parent directories with non-existent leaf paths. Attackers can craft bind source paths that appear within allowed roots but resolve outside sandbox boundaries once missing leaf components are created, weakening bind-source isolation enforcement.
CVSS 6.1
CVE-2026-27524 WRITEUP MEDIUM WRITEUP
OpenClaw < 2026.2.21 - Prototype Pollution via Debug Override Path
OpenClaw versions prior to 2026.2.21 accept prototype-reserved keys in runtime /debug set override object values, allowing prototype pollution attacks.

CVSS 4.3
CVE-2026-27545 WRITEUP MEDIUM WRITEUP
OpenClaw < 2026.2.26 - Approval Bypass via Parent Symlink Current Working Directory Rebind
OpenClaw versions prior to 2026.2.26 contain an approval bypass vulnerability in system.run execution that allows attackers to execute commands from unintended filesystem locations by rebinding writable parent symlinks in the current working directory after approval. An attacker can modify mutable parent symlink path components between approval and execution time to redirect command execution to a different location while preserving the visible working directory string.
CVSS 6.1
CVE-2026-32059 WRITEUP HIGH WRITEUP
OpenClaw <2026.2.23 - Command Injection
OpenClaw version 2026.2.22-2 prior to 2026.2.23 tools.exec.safeBins validation for sort command fails to properly validate GNU long-option abbreviations, allowing attackers to bypass denied-flag checks via abbreviated options.

OpenClaw <2026.2.2 - Command Injection
OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests (non-default configuration), allowing attackers to bypass command approval restrictions. Remote attackers can craft command strings with shell metacharacters like & or %...% to execute unapproved commands beyond the allowlisted operations.
CVSS 9.8
CVE-2026-28392 WRITEUP HIGH WRITEUP
OpenClaw <2026.2.14 - Privilege Escalation
OpenClaw versions prior to 2026.2.14 contain a privilege escalation vulnerability in the Slack slash-command handler that incorrectly authorizes any direct message sender when dmPolicy is set to open (must be configured).

OpenClaw versions prior to 2026.2.2 fail to validate webhook secrets in Telegram webhook mode (must be enabled), allowing unauthenticated HTTP POST requests to the webhook endpoint that trust attacker-controlled JSON payloads. Remote attackers can forge Telegram updates by spoofing message.from.id and chat.id fields to bypass sender allowlists and execute privileged bot commands.
CVSS 7.5
CVE-2026-28456 WRITEUP HIGH WRITEUP
OpenClaw 2026.1.5-2026.2.14 - Code Injection
OpenClaw versions 2026.1.5 prior to 2026.2.14 contain a vulnerability in the Gateway in which it does not sufficiently constrain configured hook module paths before passing them to dynamic import(), allowing code execution. An attacker with gateway configuration modification access can load and execute unintended local modules in the Node.js process.
CVSS 7.2
CVE-2026-28457 WRITEUP MEDIUM WRITEUP
OpenClaw <2026.2.14 - Path Traversal
OpenClaw versions prior to 2026.2.14 contain a path traversal vulnerability in sandbox skill mirroring (must be enabled) that uses the skill frontmatter name parameter unsanitized when copying skills into the sandbox workspace. Attackers who provide a crafted skill package with traversal sequences like ../ or absolute paths in the name field can write files outside the sandbox workspace root directory.
CVSS 6.1
CVE-2026-28458 WRITEUP HIGH WRITEUP
OpenClaw <2026.2.1 - Info Disclosure
OpenClaw version 2026.1.20 prior to 2026.2.1 contains a vulnerability in the Browser Relay (extension must be installed and enabled) /cdp WebSocket endpoint in which it does not require authentication tokens, allowing websites to connect via loopback and access sensitive data. Attackers can exploit this by connecting to ws://127.0.0.1:18792/cdp to steal session cookies and execute JavaScript in other browser tabs.
CVSS 8.1
CVE-2026-28463 WRITEUP HIGH WRITEUP
OpenClaw < 2026.2.14 - Arbitrary File Read via Shell Expansion in Exec-Approval Allowlist
OpenClaw versions prior to 2026.2.14 contain an arbitrary file read vulnerability in the exec-approvals allowlist validation that checks pre-expansion argv tokens but executes using real shell expansion. Attackers with authorization or through prompt-injection attacks can exploit safe binaries like head, tail, or grep with glob patterns or environment variables to disclose files readable by the gateway or node process when host execution is enabled in allowlist mode.
CVSS 8.4
CVE-2026-28464 WRITEUP MEDIUM WRITEUP
OpenClaw <2026.2.12 - Info Disclosure
OpenClaw versions prior to 2026.2.12 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually determine the authentication token.
