Versions 2.0.13 and below allow an unauthenticated attacker to disable CAPTCHA verification by abusing a client-controlled parameter. Because the server previously trusted this value without proper validation, CAPTCHA protections can be bypassed, enabling automated login attempts and significantly increasing the risk of account takeover (ATO). This issue is fixed in version 2.0.14.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-290","CWE-602","CWE-807"],"references":["https://github.com/1Panel-dev/1Panel/commit/ac43f00273be745f8d04b90b6e2b9c1a40ef7bca","https://github.com/1Panel-dev/1Panel/releases/tag/v2.0.14","https://github.com/1Panel-dev/1Panel/security/advisories/GHSA-qmg5-v42x-qqhq"],"products":["fit2cloud:1panel"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-66507","score":0.00467,"percentile":0.40163,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qmg5-v42x-qqhq","url":"https://osv.dev/vulnerability/GHSA-qmg5-v42x-qqhq","summary":"1Panel – CAPTCHA Bypass via Client-Controlled Flag ","modified":"2025-12-15T19:56:03.279253Z","packages":[{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel","purl":"pkg:golang/github.com/1Panel-dev/1Panel","ranges":["<2.0.14"],"fixed":["2.0.14"]},{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel/core","purl":"pkg:golang/github.com/1Panel-dev/1Panel/core","ranges":["<0.0.0-20251128030527-ac43f00273be"],"fixed":["0.0.0-20251128030527-ac43f00273be"]}]},{"id":"GO-2025-4209","url":"https://osv.dev/vulnerability/GO-2025-4209","summary":"1Panel – CAPTCHA Bypass via Client-Controlled Flag in github.com/1Panel-dev/1Panel","modified":"2026-03-03T04:57:46.115720Z","packages":[{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel","purl":"pkg:golang/github.com/1Panel-dev/1Panel","ranges":["<2.0.14+incompatible"],"fixed":["2.0.14+incompatible"]},{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel/core","purl":"pkg:golang/github.com/1Panel-dev/1Panel/core","ranges":["<0.0.0-20251128030527-ac43f00273be"],"fixed":["0.0.0-20251128030527-ac43f00273be"]}]}],"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).
