The Yak Engine has been found to contain a local file inclusion (LFI) vulnerability. This vulnerability allows attackers to include files from the server's local file system through the web application. When exploited, this can lead to the unintended exposure of sensitive data, potential remote code execution, or other security breaches. Users utilizing versions of the Yak Engine prior to 1.2.4-sp1 are impacted. This vulnerability has been patched in version 1.2.4-sp1. Users are advised to upgrade. users unable to upgrade may avoid exposing vulnerable versions to untrusted input and to closely monitor any unexpected server behavior until they can upgrade.","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-200"],"references":["https://github.com/yaklang/yaklang/pull/295","https://github.com/yaklang/yaklang/pull/296","https://github.com/yaklang/yaklang/security/advisories/GHSA-xvhg-w6qc-m3qq","https://github.com/yaklang/yaklang/pull/295","https://github.com/yaklang/yaklang/pull/296"],"products":["yaklang:yaklang"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-40023","score":0.01046,"percentile":0.64195,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xvhg-w6qc-m3qq","url":"https://osv.dev/vulnerability/GHSA-xvhg-w6qc-m3qq","summary":"Yaklang Plugin's Fuzztag Component Allows Unauthorized Local File Reading","modified":"2024-08-21T14:41:46.887971Z","packages":[{"ecosystem":"Go","name":"github.com/yaklang/yaklang","purl":"pkg:golang/github.com/yaklang/yaklang","ranges":["<1.2.4-sp2"],"fixed":["1.2.4-sp2"]}]},{"id":"GO-2023-2011","url":"https://osv.dev/vulnerability/GO-2023-2011","summary":"Yaklang Plugin's Fuzztag Component Allows Unauthorized Local File Reading in github.com/yaklang/yaklang","modified":"2026-03-03T04:55:06.606002Z","packages":[{"ecosystem":"Go","name":"github.com/yaklang/yaklang","purl":"pkg:golang/github.com/yaklang/yaklang","ranges":["<1.2.4-sp2"],"fixed":["1.2.4-sp2"]}]}],"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).
