{"id":"CVE-2026-40905","state":"PUBLISHED","title":"LinkAce: Password Reset Poisoning via X-Forwarded-Host Header Injection Leading to Account Takeover","description":"LinkAce is a self-hosted archive to collect website links. Prior to 2.5.4, a password reset poisoning vulnerability was identified in the application due to improper trust of user-controlled HTTP headers. The application uses the X-Forwarded-Host header when generating password reset URLs. By manipulating this header during a password reset request, an attacker can inject an attacker-controlled domain into the reset link sent via email. As a result, the victim receives a password reset email containing a malicious link pointing to an attacker-controlled domain. When the victim clicks the link, the password reset token is transmitted to the attacker-controlled server. An attacker can capture this token and use it to reset the victim’s password, leading to full account takeover. This vulnerability is fixed in 2.5.4.","publishedAt":"2026-04-21T20:02:35.006Z","updatedAt":"2026-04-21T20:35:49.598Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Kovah LinkAce"],"affected":[{"vendor":"Kovah","product":"LinkAce","versions":[{"version":"< 2.5.4","status":"affected"}]}],"references":["https://github.com/Kovah/LinkAce/security/advisories/GHSA-48wv-jpf4-vjfv"],"weaknesses":["CWE-601"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/40xxx/CVE-2026-40905.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-40905","state":"PUBLISHED","datePublished":"2026-04-21T20:02:35.006Z","dateUpdated":"2026-04-21T20:35:49.598Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-15T16:37:22.767Z"},"containers":{"cna":{"title":"LinkAce: Password Reset Poisoning via X-Forwarded-Host Header Injection Leading to Account Takeover","descriptions":[{"lang":"en","value":"LinkAce is a self-hosted archive to collect website links.
