Prior to version 0.1.4, five debug/test PHP scripts under `admin/` perform privileged operations without `isLoggedIn()` authentication checks, CSRF protection or adequate `path` validation. On PHP's built-in development server, including the default Docker deployment, `router.php` checks an unnormalized admin URI prefix while the filesystem resolves dot segments, so `/./admin/` bypasses the admin login gate and executes those scripts directly. In `admin/debug_save_flow.php`, attacker-controlled `path` and `content` reach `file_put_contents` for arbitrary `.md` writes under `content`/ or outside it through `path` traversal, enabling site defacement and stored JavaScript in public pages; `print_r($_POST)` output without `htmlspecialchars` escaping also causes reflected cross-site scripting. The `admin/debug_content.php` `path` parameter reaches `scandir()`, `file_get_contents()` and `posix_getpwuid()`, permitting arbitrary directory enumeration and `.md` file reads that expose absolute paths, ownership, permissions, hashes and `content` previews. The `admin/preview-handler.php` endpoint accepts JSON `content` and `title` and writes enumerable files under `content/_preview/`, enabling stored cross-site scripting and disk exhaustion. The `admin/testdebug.php` endpoint appends to `admin/testdebug.log` without authentication, also enabling disk exhaustion. The `admin/test_redirect.php` script exposes a test artifact but escapes its inputs and is not itself an XSS sink. Stored script execution can steal sessions and compromise administrators when they view affected `content`. Reads and writes execute with PHP's privileges; the tested deployment runs PHP as root, amplifying filesystem impact. This issue is fixed in version 0.1.4.\nhttps://www.cve.org/CVERecord?id=CVE-2026-63190https://github.com/fearlessgeekmedia/FearlessCMS/security/advisories/GHSA-3mq8-hrhf-7hv6https://github.com/fearlessgeekmedia/FearlessCMS/commit/59fb22cf989b5ba14c387c3212e15b146e02cf9ahttps://github.com/fearlessgeekmedia/FearlessCMS/tree/0.1.4#fearlessgeekmedia #FearlessCMS#CVE_2026_63190#bot", "url": "https://infosec.exchange/users/cve/statuses/117520196709068809"}, {"timestamp": "2026-10-28T20:00:04.898Z", "date_only": false, "value": "2026-10-28T20:00:04.898538Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stackflag.bsky.social/post/3myxk36shz72v", "record": "CVE-2026-63190", "field": "creation_timestamp", "uuid": "16d4550a-0a89-440d-9b76-4451b620cc04", "content": "CVE-2026-63190 - fearlesscms\nEarlier versions of FearlessCMS let anyone access hidden admin scripts without logging in, letting them create or modify files and run malicious code on the site.\u2026\n\nToo many irrelevant or confusing CVEs?
