{"id":"CVE-2026-40905","summary":"LinkAce: Password Reset Poisoning via X-Forwarded-Host Header Injection Leading to Account Takeover","details":"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.","aliases":["GHSA-48wv-jpf4-vjfv"],"modified":"2026-08-12T03:51:25.877562308Z","published":"2026-04-21T20:02:35.006Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-601"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40905.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40905.json"},{"type":"ADVISORY","url":"https://github.com/Kovah/LinkAce/security/advisories/GHSA-48wv-jpf4-vjfv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40905"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kovah/linkace","events":[{"introduced":"0"},{"fixed":"d0a05d12a4d0b14059aef009552ceabaf9f64563"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"2.5.4"}]}}],"versions":["v2.5.3","v2.5.2","v2.5.1","v2.5.0","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.0","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.0","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta1","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.0","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.1","v1.0.0","v0.0.44","v0.0.43","v0.0.42","v0.0.41","v0.0.40","v0.0.39","v0.0.38","v0.0.37","v0.0.36","v0.0.35","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40905.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
