No CVSS score has been assigned to CVE-2026-32980 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-32980?

CVE-2026-32980 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-32980?

Update openclaw to 2026.3.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32980 is resolved across your whole dependency graph.

How do I detect CVE-2026-32980 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-32980 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is CVE-2026-32980 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32980 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-32980?

CVE-2026-32980 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 46th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-32980?

CVE-2026-32980 is classified as CWE-770 (CWE-770). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-32980 published, and has it been updated?

CVE-2026-32980 was published on March 29, 2026 and was last updated on November 4, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

openclaw versions <= 2026.3.12 read and buffered Telegram webhook request bodies before validating x-telegram-bot-api-secret-token. This let unauthenticated callers force up to the configured webhook body limit of pre-auth body I/O and JSON parse work per request.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.3.12
Fixed version: 2026.3.13

Details

The vulnerable path was the standalone Telegram webhook listener in src/telegram/webhook.ts. In affected releases, the request handler accepted POST requests, called readJsonBodyWithLimit(...), and only then checked the Telegram secret header. Because the secret validation happened after body reading, an unauthenticated caller could make the server spend memory, socket time, and JSON parse work on requests that should have been rejected before any body processing.

This issue is in scope under OpenClaw's trust model because the Telegram webhook endpoint accepts untrusted network traffic and the secret header is the authentication boundary for that ingress path.

Fix

[email protected] validates the Telegram webhook secret before any body I/O. Current code reads the header, rejects invalid requests immediately with 401, and only calls readJsonBodyWithLimit(...) after hasValidTelegramWebhookSecret(...) succeeds.

Regression coverage exists in src/telegram/webhook.test.ts (rejects unauthenticated requests before reading the request body).
