CVE-2026-35467: CWE-522 Insufficiently Protected Credentials in CERT/CC cveClient/encrypt-storage.js
CVE-2026-35467 is a high-severity vulnerability in the CERT/CC cveClient/encrypt-storage. js component where API keys stored in the temporary browser client are insufficiently protected. The encryption credentials are not properly marked as protected, which could allow extraction through JavaScript console access or other errors. This vulnerability has a CVSS score of 7. 5, indicating a significant confidentiality impact without requiring privileges or user interaction. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-35467) involves insufficient protection of stored API keys in the temporary browser client of CERT/CC's cveClient/encrypt-storage.js. The encryption credentials are not marked as protected, enabling potential extraction via JavaScript console or error conditions. The CVSS 3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting a network attack vector with low complexity, no privileges or user interaction required, and a high confidentiality impact. No patch or vendor advisory is currently available, and the product is not a cloud service.
Potential Impact
An attacker with network access could extract encryption credentials from the temporary browser client due to insufficient protection of stored API keys. This leads to a high confidentiality impact as sensitive API keys may be exposed. There is no impact on integrity or availability reported. No known exploits are currently active in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit exposure by restricting access to the browser client environment and avoid running untrusted scripts that could access the JavaScript console. Monitor for updates from CERT/CC regarding patches or mitigations.
