Prior to 0.18.0, the ImageMagick converter uses the unsanitized convert_to parameter to construct an output path. If an authenticated user, or an unauthenticated user when ConvertX is configured to allow unauthenticated access, uploads an extensionless image and supplies directory traversal sequences in convert_to through /convert, the constructed path escapes the intended output directory, allowing the attacker to write converted output to arbitrary container paths, potentially overwriting files or causing denial of service. This issue is fixed in version 0.18.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22","CWE-73"],"references":["https://github.com/C4illin/ConvertX/commit/0965928949319e2839770fbf57a8337440d42630","https://github.com/C4illin/ConvertX/pull/532","https://github.com/C4illin/ConvertX/releases/tag/v0.18.0","https://github.com/C4illin/ConvertX/security/advisories/GHSA-pvqw-vc5x-266j","https://github.com/C4illin/ConvertX/security/advisories/GHSA-pvqw-vc5x-266j"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-59976","score":0.00769,"percentile":0.55318,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
