Craft CMS versions from 5.7.0 before 5.10.13 contain a stored cross-site scripting vulnerability in the Generated Fields feature that disables Twig autoescaping and fails to encode cached values. Content editors can inject malicious JavaScript through editable fields that executes in authenticated Control Panel sessions of higher-privileged users viewing element indexes.
AnalysisAI
Stored cross-site scripting in Craft CMS (5.7.0 through 5.10.12) allows an authenticated content editor to plant malicious JavaScript that executes in the Control Panel session of a higher-privileged user who views the affected element index. The flaw lives in the Generated Fields feature, which disables Twig autoescaping and caches field values without encoding, so injected markup is served raw; exploitation requires an editor-level account (PR:L), the optional Generated Fields feature to be in use, and the victim to open the index (UI:P), and the resulting impact is confined to the victim's browser session with no server-side confidentiality, integrity, or availability loss. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the Generated Fields feature to be in use on element(s) exposed via an element index, since that feature is what disables Twig autoescaping and stores un-encoded cached values. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but modest-severity stored XSS, not a top-priority emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Craft CMS to 5.10.13 or later - the vendor-released patch for this issue - and confirm the deployment actually runs the patched code after any Composer update. … Detailed patch versions, workarounds, and compensating controls in full report. |
