Summary

Risk Assessment

Attackers can use the publicly visible file hash to retrieve the delete_code via the info API and then invoke the delete API to permanently delete arbitrary files, while also exposing uploader IP, User Agent, remote port, and SHA-1 hash, resulting in loss of content integrity, availability, and uploader privacy.

Recommendation

Upgrade PictShare to version 3.7.1 or later. Until patched, restrict access to the API::info() endpoint and consider disabling public file sharing.

Other vulnerabilities in PictShare

CVE-2026-104356Medium
PictShare before version 3.7.1 contains a weak randomness vulnerability where the getRandomString() function uses the non-cryptographic rand() PRNG to generate the delete_code authorization token in src/inc/core.php. Attackers can predict or infer the PRNG state to guess valid delete_code values and perform unauthorized deletion of hosted files without needing to read the code from the info endpoint.

Original NVD description (English source)

PictShare before 3.7.1 contains an information disclosure vulnerability that allows unauthenticated attackers to obtain the secret delete_code and uploader metadata by calling the API::info() endpoint which returns the complete raw metadata object without a field whitelist. Attackers can use the publicly visible file hash to retrieve the delete_code via the info API and then invoke the delete API to permanently delete arbitrary files, while also exposing uploader IP, User Agent, remote port, and SHA-1 hash, resulting in loss of content integrity, availability, and uploader privacy.
