Description

Papra is a minimalistic document management and archiving platform. Prior to 26.4.0, API keys with an expiresAt date are never validated against the current time during authentication. Any API key — regardless of its expiration date — is accepted indefinitely, allowing a user whose key has expired to continue accessing all protected endpoints as if the key were still valid. This vulnerability is fixed in 26.4.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.
