Title

Laravel MagicLink: Insecure Deserialization of MagicLink Actions Leads to Remote Code Execution

Summary

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.

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."

GHSA-R33W-FG8J-9C94

Vulnerability from github – Published: 2026-02-12 22:11 – Updated: 2026-02-12 22:11

Summary

MagicLink: Insecure Deserialization of MagicLink Actions Leads to Remote Code Execution

Details

Description

MagicLink stores serialized action objects in the magic_links.action database column and deserializes them without integrity validation or class allowlisting in src/MagicLink.php and src/Actions/ResponseAction.php. An attacker with the ability to manipulate database records (e.g., via SQL injection or compromised admin access) could inject malicious serialized objects containing arbitrary closures, leading to Remote Code Execution (RCE) when the magic link is visited.

Resolution

The vulnerability has been mitigated through HMAC-signed serialization using the application key, class allowlisting restricted to ActionAbstract subclasses and framework classes, strict type validation preventing arbitrary object storage, and backward compatibility support for legacy data via allowed_classes in unserialize(). Implementation includes a new Serializable security class with signing/verification, refactored getter/setter methods in MagicLink.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
