Which packages are affected by GHSA-p8x7-9vfw-p7vc?

GHSA-p8x7-9vfw-p7vc affects the following packages: craftcms/cms (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-p8x7-9vfw-p7vc?

Update craftcms/cms to 5.10.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p8x7-9vfw-p7vc is resolved across your whole dependency graph.

How do I detect GHSA-p8x7-9vfw-p7vc in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-p8x7-9vfw-p7vc if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-p8x7-9vfw-p7vc actively exploited in the wild?

No public exploit code has been indexed for GHSA-p8x7-9vfw-p7vc yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-p8x7-9vfw-p7vc?

GHSA-p8x7-9vfw-p7vc has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 40th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-p8x7-9vfw-p7vc?

GHSA-p8x7-9vfw-p7vc is classified as CWE-285 (CWE-285). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

The vulnerability allows any authenticated user to change their own password without providing the current password or having an active elevated session. It also allows the attacker to change other users’ passwords if the attacker’s account has edit users permission (which doesn’t allow changing others’ passwords) and lacks Administrate users permission (which is required to change others’ passwords).

The vulnerability exists in the elements/save action when saving a User element. The UserPasswordValidator applies only a safe validator to the newPassword field without an on scenario restriction. This makes newPassword mass-assignable during the generic element save flow, completely bypassing the dedicated users/set-password action that enforces elevated session verification.

An attacker with any authenticated session (whether it’s hijacked or a normal / low-privileged user) can change their own password, and potentially take over administrator accounts.

Required Permissions

Access the control panel
Edit users (needed for the account takeover attack scenario)

Impact

Any authenticated user can change their own password without providing their current password.
Users with Edit users permission can change any user’s password, including administrators.

Frequently Asked Questions

The vulnerability allows any authenticated user to change their own password without providing the current password or having an active elevated session. It also allows the attacker to change other users’ passwords if the attacker’s account has `edit users` permission (which doesn’t allow changing others’ passwords) and lacks `Administrate users` permission (which is required to change others’ passwords). The vulnerability exists in the `elements/save` action when saving a User element. The `UserPasswordValidator` applies only a `safe` validator to the `newPassword` field without an `on` scen
