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.","cvssScore":8.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","cwes":["CWE-522"],"vendors":[],"products":[],"references":[{"url":"https://github.com/HaschekSolutions/pictshare/commit/ce5fc474e89769efeae25fee763894bcce3412e3","tags":[]},{"url":"https://github.com/HaschekSolutions/pictshare/releases/tag/v3.7.1","tags":[]},{"url":"https://www.vulncheck.com/advisories/pictshare-sensitive-information-disclosure-via-info-api","tags":[]}],"exploitRefs":[{"url":"https://github.com/HaschekSolutions/pictshare/commit/ce5fc474e89769efeae25fee763894bcce3412e3","tags":[]},{"url":"https://github.com/HaschekSolutions/pictshare/releases/tag/v3.7.1","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows unauthenticated attackers to retrieve sensitive metadata and delete arbitrary files, compromising content integrity and uploader privacy.","exploitability":"Exploitation is relatively straightforward given the public API endpoint and requires knowledge of the file hash.","blast_radius":"If exploited, attackers can permanently delete files and expose uploader details, leading to significant data loss and privacy breaches.","remediation":"Upgrade to PictShare 3.7.1 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["info-disc","delete-code","metadata-exposure","file-deletion"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-05T08:43:24.390Z"}}
