{"id":"GHSA-cg4f-cq8h-3ch8","aliases":["CVE-2025-46350"],"title":"Yeswiki Vulnerable to Authenticated Reflected Cross-site Scripting","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"LOW","description":"### Summary\n**Vulnerable Version:** Yeswiki < v4.5.4\n**Vulnerable Endpoint:** `/?PagePrincipale%2Fdeletepage`\n**Vulnerable Parameter:** `incomingurl`\n**Payload:** `\"><script>alert(1)</script>`\n\n### Details\nReflected Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser-side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it.\n\n### PoC\n**NOTE:** This vulnerability requires admin access.\n1. Visit the endpoint as mentioned below and see that an alert box pops up:\n\n   **URL with Payload:** `https://yeswiki.net/?PagePrincipale%2Fdeletepage&incomingurl=\"><script>alert(1)</script>`\n\n### Impact\nAn attacker can use a reflected cross-site scripting attack to steal cookies from an authenticated user by having them click on a malicious link. Stolen cookies allow the attacker to take over the user’s session. This vulnerability may also allow attackers to deface the website or embed malicious content.","severity":"low","score":3.8,"published":"2025-04-29T14:37:04.000Z","modified":"2026-09-10T03:50:23.732Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"yeswiki/yeswiki","sources":[{"name":"OSV · GHSA-cg4f-cq8h-3ch8","url":"https://osv.dev/vulnerability/GHSA-cg4f-cq8h-3ch8"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"4.5.4"}],"type":"ECOSYSTEM"}],"versions":["4.2.3","v4.1.0","v4.1.1","v4.1.2","v4.1.3","v4.1.4","v4.1.5","v4.2.0","v4.2.1","v4.2.2","v4.2.4","v4.3","v4.3.1","v4.4.0","v4.4.1","v4.4.2","v4.4.3","v4.4.4","v4.4.5","v4.5.0","v4.5.1","v4.5.2","v4.5.3"],"fixed":["4.5.4"]}],"sourceAffected":[],"references":["https://github.com/YesWiki/yeswiki/security/advisories/GHSA-cg4f-cq8h-3ch8","https://nvd.nist.gov/vuln/detail/CVE-2025-46350","https://github.com/YesWiki/yeswiki/commit/e2603176a4607b83659635a0c517550d4a171cb9","https://github.com/YesWiki/yeswiki"],"sources":[{"name":"OSV","id":"GHSA-cg4f-cq8h-3ch8","modified":"2026-09-10T03:50:23.732808172Z","url":"https://osv.dev/vulnerability/GHSA-cg4f-cq8h-3ch8"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N","score":3.8}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:15:33.378Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
