{"id":"CVE-2026-112106","kind":"vulnerability","aliases":["CVE-2026-112106"],"related":[],"title":"TikTok-Video-Downloader-PHP: improper TLS certificate validation in index.php","description":"A security vulnerability has been detected in TufayelLUS TikTok-Video-Downloader-PHP up to c4230497bb23dd9c1f81456fe8a982d951feac0d. Affected by this issue is some unknown functionality of the file index.php of the component TLS Handler. Such manipulation leads to improper certificate validation. It is possible to launch the attack remotely. The attack requires a high level of complexity. The exploitation is known to be difficult. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The name of the patch is 64c0155abb88e714198241d41b918cefc0d5a42a. It is advisable to implement a patch to correct this issue.","summary":"The TLS handler in index.php of TikTok-Video-Downloader-PHP does not properly validate certificates, so connections can be impersonated.
