Summary

CVE-2024-13919 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Laravel Framework. Its CVSS base score is 8.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Spearphishing Link (T1566.002); ranked in the top 42.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-11 (Error Handling) and SI-15 (Information Output Filtering).

Deeper analysis

CVE-2024-13919 is a reflected cross-site scripting (XSS) vulnerability affecting the Laravel framework in versions 11.9.0 through 11.35.1. The issue stems from improper encoding of route parameters when displayed on the debug-mode error page, allowing malicious scripts to be injected and executed. It carries a CVSS v3.1 base score of 8.0 (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N) and maps to CWE-79.

An unauthenticated remote attacker can exploit this vulnerability by tricking a user into accessing a specially crafted URL that triggers an error page in debug mode. The unencoded route parameter reflects the attacker's payload, enabling script execution in the victim's browser context with high confidentiality and integrity impacts, such as session hijacking or data theft, though it requires user interaction and high attack complexity.

Mitigation involves upgrading to Laravel framework version 11.36.0 or later, where the fix is implemented via pull request #53869 on GitHub. Further details on the vulnerability and remediation are provided in the SBA advisory at sbaresearch GitHub and the oss-security mailing list announcement.
