CVE-2026-25474

In Telegram webhook mode, if channels.telegram.webhookSecret is not set, OpenClaw may accept webhook HTTP requests without verifying Telegram’s secret token header. In deployments where the webhook endpoint is reachable by an attacker, this can allow forged Telegram updates (for example spoofing message.from.id).

Note: Telegram webhook mode is not enabled by default. It is enabled only when channels.telegram.webhookUrl is configured.

Affected Packages / Versions

• Package: openclaw (npm)
• Affected: <= 2026.1.30
• Patched: >= 2026.2.1

Mitigations / Workarounds

• Set a strong channels.telegram.webhookSecret and ensure your reverse proxy forwards the X-Telegram-Bot-Api-Secret-Token header unchanged.
• Restrict network access to the webhook endpoint (for example bind to loopback and only expose via a reverse proxy).

Fix Commit(s)

• ca92597e1f9593236ad86810b66633144b69314d (config validation: webhookUrl requires webhookSecret)

Defense-in-depth / supporting fixes:

• 5643a934799dc523ec2ef18c007e1aa2c386b670 (default webhook listener bind host to loopback)
• 3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930 (bound webhook request body size/time)
• 633fe8b9c17f02fcc68ecdb5ec212a5ace932f09 (runtime guard: reject webhook startup when secret is missing/empty)

Thanks @yueyueL for reporting.

If an attacker can reach the webhook endpoint, they may be able to send forged updates that are processed as if they came from Telegram. Depending on enabled commands/tools and configuration, this could lead to unintended bot actions.

CVE-2026-25474 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2026.2.1); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2026-25474? CVE-2026-25474 is a high-severity security vulnerability in openclaw (npm), affecting versions < 2026.2.1. It is fixed in 2026.2.1.
2. How severe is CVE-2026-25474? CVE-2026-25474 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of openclaw are affected by CVE-2026-25474? openclaw (npm) versions < 2026.2.1 is affected.
4. Is there a fix for CVE-2026-25474? Yes. CVE-2026-25474 is fixed in 2026.2.1. Upgrade to this version or later.
5. Is CVE-2026-25474 exploitable, and should I be worried? Whether CVE-2026-25474 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-25474 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-25474? Upgrade openclaw to 2026.2.1 or later.
