{"id":"GHSA-cg4f-cq8h-3ch8","summary":"Yeswiki Vulnerable to Authenticated Reflected Cross-site Scripting","details":"### Summary\n**Vulnerable Version:** Yeswiki \u003c v4.5.4\n**Vulnerable Endpoint:** `/?PagePrincipale%2Fdeletepage`\n**Vulnerable Parameter:** `incomingurl`\n**Payload:** `\"\u003e\u003cscript\u003ealert(1)\u003c/script\u003e`\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=\"\u003e\u003cscript\u003ealert(1)\u003c/script\u003e`\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.","aliases":["CVE-2025-46350"],"modified":"2026-09-10T03:50:23.732808172Z","published":"2025-04-29T14:37:04Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2025-04-29T14:37:04Z","nvd_published_at":"2025-04-29T18:15:44Z","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-cg4f-cq8h-3ch8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-46350"},{"type":"WEB","url":"https://github.com/YesWiki/yeswiki/commit/e2603176a4607b83659635a0c517550d4a171cb9"},{"type":"PACKAGE","url":"https://github.com/YesWiki/yeswiki"}],"affected":[{"package":{"name":"yeswiki/yeswiki","ecosystem":"Packagist","purl":"pkg:composer/yeswiki/yeswiki"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.4"}]}],"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"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/04/GHSA-cg4f-cq8h-3ch8/GHSA-cg4f-cq8h-3ch8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N"}]}
