How severe is CVE-2026-32231?

CVE-2026-32231 has a CVSS score of 8.2/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2026-32231?

CVE-2026-32231 affects the following packages: zeptoclaw (crates.io). Ecosystems affected: crates.io.

How do I fix CVE-2026-32231?

Update zeptoclaw to 0.7.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32231 is resolved across your whole dependency graph.

How do I detect CVE-2026-32231 in my crates.io dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zeptoclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-32231 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-32231?

O3 pinpoints whether CVE-2026-32231 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-32231 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32231 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-2026-32231?

CVE-2026-32231 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 8th 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-2026-32231?

CVE-2026-32231 is classified as Missing Authentication (CWE-306), CWE-345 (CWE-345). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-32231 published, and has it been updated?

CVE-2026-32231 was published on March 12, 2026 and was last updated on April 10, 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

ZeptoClaw is a personal AI assistant. Prior to 0.7.6, the generic webhook channel trusts caller-supplied identity fields (sender, chat_id) from the request body and applies authorization checks to those untrusted values. Because authentication is optional and defaults to disabled (auth_token: None), an attacker who can reach POST /webhook can spoof an allowlisted sender and choose arbitrary chat_id values, enabling high-risk message spoofing and potential IDOR-style session/chat routing abuse. This vulnerability is fixed in 0.7.6.
