{"cve":"CVE-2026-45087","nvd":{"published":"2026-05-27T18:16:24.567","modified":"2026-10-26T11:10:00.157","status":"Deferred","description":"Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is started in REST API server mode (dalfox server), the server binds to 0.0.0.0:6664 by default and requires no API key unless the operator explicitly passes --api-key. Because model.Options — including FoundAction and FoundActionShell — is deserialized directly from attacker-supplied JSON in POST /scan, and because dalfox.Initialize explicitly propagates those two fields into the final scan options without stripping them, any unauthenticated caller who can reach the server port can supply an arbitrary shell command that the dalfox process will execute on the host whenever a scan finding is triggered. This vulnerability is fixed in 2.13.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-15","CWE-78","CWE-306"],"references":["https://github.com/hahwul/dalfox/releases/tag/v2.13.0","https://github.com/hahwul/dalfox/security/advisories/GHSA-v25v-m36w-jp4h","https://github.com/hahwul/dalfox/security/advisories/GHSA-v25v-m36w-jp4h"],"products":[],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-45087","score":0.08731,"percentile":0.95112,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v25v-m36w-jp4h","url":"https://osv.dev/vulnerability/GHSA-v25v-m36w-jp4h","summary":"Dalfox Server Mode Vulnerable to Unauthenticated Remote Code Execution via `found-action`","modified":"2026-06-25T23:11:32.811626362Z","packages":[{"ecosystem":"Go","name":"github.com/hahwul/dalfox/v2","purl":"pkg:golang/github.com/hahwul/dalfox/v2","ranges":["<2.13.0"],"fixed":["2.13.0"]}]},{"id":"GO-2026-5649","url":"https://osv.dev/vulnerability/GO-2026-5649","summary":"Dalfox Server Mode Vulnerable to Unauthenticated Remote Code Execution via `found-action` in github.com/hahwul/dalfox","modified":"2026-06-25T23:01:36.666541547Z","packages":[{"ecosystem":"Go","name":"github.com/hahwul/dalfox","purl":"pkg:golang/github.com/hahwul/dalfox","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/hahwul/dalfox/v2","purl":"pkg:golang/github.com/hahwul/dalfox/v2","ranges":["<2.13.0"],"fixed":["2.13.0"]}]}],"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).
