How to Fix CVE-2026-27003

To remediate this vulnerability, upgrade all affected OpenClaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.2.15 
npm install openclaw@2026.2.15
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-27003, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of OpenClaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.15), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. In OpenClaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Vulnerability Telegram bot tokens can appear in error messages and stack traces (for example, when request URLs include `https://api.telegram.org/bot<token>/...`). OpenClaw previously logged these strings without redaction, which could leak the bot token into logs, crash reports, CI output, or support bundles. ## Impact Disclosure of a Telegram bot token allows an attacker to impersonate the bot and take over Bot API access. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.14` - Fixed: `>= 2026.2.15` (next release) ## Mitigation - Upgrade to `openclaw >= 2026.2.15` when released. - Rotate the Telegram bot token if it may have been exposed. ## Fix Commit(s) - cf6990701b258bb9cc4ac7f6c7bdf05016e7f6e46 Thanks @aether-ai-agent for reporting.
