CVE-2026-104356: Hascheksolutions Pictshare

Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Hascheksolutions Pictshare: from 2.0.0, before 3.7.1 (fixed in 3.7.1)
