Packagist
PKSA-zrgd-gjq7-6ykr
Reported
Aug 6, 2020

Affected and fixed versions

In 2 packages: illuminate/database and laravel/framework. Find the row for the version you run, and update to the release next to it.

If you run Update to Support
7.0.0 – 7.23.1 7.23.2
6.0.0 – 6.18.33 6.18.34
5.5.0 – 5.5.44 No fix yet
Show 1 older branch
5.5.0 – 5.5.49 No fix

Upgrade

Run the line for the branch you are on. 1 other package listed above is affected too; update it the same way.

composer require laravel/framework:^7.23.2
composer require laravel/framework:^6.18.34

Check your app with an agent

Paste this into a coding agent that can read your project, such as Claude Code, Codex or Amp. It checks your composer.lock against the versions above and tells you what to update, without changing anything.

Check whether the PHP project you have access to is affected by this security advisory, and tell me what to update. Do a read-only check: don't edit files, don't run composer update or composer require, and don't try to reproduce the flaw.

Advisory: Guard bypass in Eloquent models (CVE-2020-24940, GHSA-qm5c-m76r-2hfr)
Details: https://phpnews.net/security/laravel/ghsa-qm5c-m76r-2hfr

Affected versions, as Composer constraints:
- illuminate/database: >=5.5.0,<=5.5.44|>=6.0.0,<6.18.34|>=7.0.0,<7.23.2
- laravel/framework: >=5.5.0,<=5.5.49|>=6.0.0,<6.18.34|>=7.0.0,<7.23.2

Fixed releases:
- 7.0.0 – 7.23.1: update to 7.23.2
- 6.0.0 – 6.18.33: update to 6.18.34
- 5.5.0 – 5.5.44: no fixed release yet

1. Find every composer.lock in the project outside vendor/ (a monorepo can have one per app) and read the installed version of each package above. Packages installed as dependencies of other packages count too.
2. Compare each installed version with its constraint: "|" separates alternative ranges, and "," means both bounds apply.
3. For each affected install, read the project's advisory at https://blog.laravel.com/security-release-laravel-61834-7232 and check whether the project meets the conditions it describes (if that page won't load, use https://github.com/advisories/GHSA-qm5c-m76r-2hfr). Say which conditions you could check and which you couldn't.
4. Report a table: lock file | package | installed version | affected (yes, no or unknown) | conditions met (yes, no or unknown) | update to | evidence. For each affected package, give the command that would fix it, without running it: composer update <package> --with-dependencies when it is only installed as a dependency of another package, or composer require with the fixed version when composer.json requires it directly. If the installed version is on a branch with no fixed release listed, say it needs a move to a newer branch.
