This means expired API keys remain valid indefinitely, allowing continued access to protected endpoints. The issue is identified as insufficient session expiration (CWE-613) and is fixed in version 26. 4. 0. The vulnerability has a medium severity with a CVSS score of 4. 3.
AI Analysis
Technical Summary
CVE-2026-35462 affects papra, a document management platform, by failing to enforce expiration on API keys. Specifically, API keys that include an expiresAt date are accepted regardless of whether they have expired, due to lack of validation against the current time during authentication. This allows users with expired keys to maintain access to all protected API endpoints indefinitely. The vulnerability is resolved in papra version 26.4.0.
Potential Impact
Users with expired API keys can continue to access protected endpoints as if their keys were still valid, potentially leading to unauthorized access beyond the intended expiration period. The impact is limited to confidentiality (partial disclosure risk) with no integrity or availability impact reported. The CVSS score of 4.3 reflects a medium severity level.
Mitigation Recommendations
Upgrade papra to version 26.4.0 or later, where the issue is fixed by proper validation of API key expiration dates during authentication. Since the vendor has fixed the vulnerability in this version, applying this official fix is the recommended remediation. Patch status is confirmed by the vendor advisory stating the fix is included in version 26.4.0.
