SCA: security update for getgrav/grav (GHSA-pmf8-g7c8-7v54)

medium Tenable Cloud Security Plugin ID 443495

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Grav is a file-based Web platform. Prior to 2.0.0-rc.9, Grav's incomplete fix for stored XSS through the
Markdown media attribute action (CVE-2026-42841) leaves the sibling MediaObjectTrait::style method
reachable through the same Markdown excerpt-action pipeline, allowing an editor to save Markdown image
style parameters that are written into the rendered img style attribute without sanitization. This issue
is fixed in version 2.0.0-rc.9. (CVE-2026-55890)

Solution

Update the getgrav/grav library and its related packages to version 2.0.0-rc.9 or later.
