CVE-2024-24570: Statamic account takeover via XSS and password reset link
Impact
HTML files crafted to look like jpg files are able to be uploaded, allowing for XSS.
This affects:
- front-end forms with asset fields without any mime type validation - asset fields in the control panel - asset browser in the control panel
Additionally, if the XSS is crafted in a specific way, the "copy password reset link" feature may be exploited to gain access to a user's password reset token and gain access to their account. The authorized user is required to execute the XSS in order for the vulnerability to occur.
Patches
In versions 4.46.0 and 3.4.17, the XSS vulnerability has been patched, and the copy password reset link functionality has been disabled. (Users may still trigger password reset emails.)
