| CVE-2026-42844 | Grav is a file-based Web platform. In Grav 2.0.0-beta.2, a low-privileged authenticated API user with api.media.write can abuse /api/v1/blueprint-upload to write an arbitrary YAML file into user/accounts/, then log in as the newly created account with api.super privileges. This results in full administrative compromise of the Grav API. This vulnerability is fixed in API 1.0.0-beta.17. | [email protected] | 8.7 | 0.34% | 2026-05-12 | 2026-06-17 |
| CVE-2026-44738 | Grav is a file-based Web platform. Prior to 2.0.0-rc.2, the Twig sandbox allow-list permits any user with the admin.pages role to call config.toArray() from within a page body, dumping the entire merged site configuration — including all plugin secrets (SMTP passwords, AWS keys, OAuth client secrets, API tokens) — into the rendered HTML. No administrator privileges are required. This vulnerability is fixed in 2.0.0-rc.2. | [email protected] | 7.7 | 0.28% | 2026-05-11 | 2026-06-17 |
