Detailsinfo

A vulnerability, which was classified as critical, was found in cesargb laravel-magiclink up to 2.25.0. Affected is the function unserialize of the file src/MagicLink.php of the component Action Deserialization. The manipulation with an unknown input leads to a deserialization vulnerability. CWE is classifying the issue as CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Laravel MagicLink creates links for authentication without a password or for accessing private content. From 2.0.0 until 2.25.1, MagicLink stores serialized action objects in the magic_links.action database column and deserializes them through src/MagicLink.php and src/Actions/ResponseAction.php without sufficient integrity protection, while an unsafe legacy unserialize() fallback remains reachable. An attacker who can manipulate database records, such as through a separate SQL injection or compromised administrative access, can insert a malicious serialized object graph containing executable closure behavior; visiting the associated magic link then deserializes the record and can execute arbitrary code in the application process. The affected path is restricted to manipulated action records and does not independently provide database-write access. This issue is fixed in version 2.25.1.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-61701 since 07/10/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.
