CVE-2026-61844
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
Prior to 3.18.0, FileRise flattens logical folder paths into metadata filenames by replacing separators and spaces with hyphens, so distinct folders such as team/docs and team-docs can share one metadata file. A low-privileged user who controls one colliding folder and knows the target basename can alter the metadata, make the victim file appear attacker-owned, then read and modify it.
Risk Assessment
A low-privileged authenticated user can bypass read_own and edit_own access controls, gaining unauthorized access to and modification of other users' files.
Recommendation
Upgrade FileRise to version 3.18.0 or later, which removes the metadata filename collisions.
Other vulnerabilities in FileRise
See all- CVE-2026-92616Medium
FileRise before version 3.28.0 contains a privilege escalation vulnerability that allows authenticated low-privilege attackers to gain unauthorized read and write access by exploiting improper session isolation between the WebDAV interface and the web application session context. Attackers can combine valid Basic-Auth credentials with an active admin PHPSESSID cookie to bypass authorization boundaries.
- CVE-2026-54414Critical
FileRise before 3.16.0 is vulnerable to path traversal in the shared-folder upload endpoint (/api/folder/uploadToSharedFolder.php), leading to arbitrary file write and administrator account takeover. The upload filename validation permits URL-encoded sequences.
- CVE-2026-77427Medium
FileRise is a self-hosted web-based file manager. From 3.9.0 until 3.22.0, pristine manual FileRise installations without PERSISTENT_TOKENS_KEY or metadata/persistent_tokens.key can activate a published legacy compatibility key. If an attacker separately obtains ciphertext-bearing account or configuration files, the known fallback key can enable decryption of TOTP secrets or credentials. This issue is fixed in version 3.22.0.
- CVE-2026-69194Medium
FileRise is a self-hosted web-based file manager. Prior to 3.21.0, FileRise returns the stored branding.footerHtml value through the unauthenticated public site configuration API without server-side sanitization. The FileRise frontend already sanitizes this value before rendering it into the page, but the unauthenticated public config API exposed raw admin-provided footer HTML to clients. An administrator must first store the malicious footer value. This issue is fixed in version 3.21.0.
- CVE-2026-69193Medium
FileRise is a self-hosted web-based file manager. Prior to 3.21.0, FileRise tracks failed logins only by the combination of source IP address and username. A remote unauthenticated attacker can rotate usernames to obtain a fresh per-account attempt budget for each name, enabling password spraying from one source beyond the intended limit. This issue is fixed in version 3.21.0.
- CVE-2026-69191Medium
FileRise is a self-hosted web-based file manager. Prior to 3.21.0, FileRise enforces disableFormLogin, disableBasicAuth, and disableOIDCLogin in the client interface but not consistently in the corresponding server-side authentication flows. A user with otherwise valid credentials for a disabled method can call its backend endpoint directly and authenticate despite the administrator's login-method policy. This issue is fixed in version 3.21.0.
- CVE-2026-64856Low
Prior to 3.20.0, FileRise /api/file/snippet.php does not apply the standard authenticated-session guard before processing short text preview requests. The endpoint still performs FileRise ACL checks, so normal installations do not expose an unauthenticated arbitrary file read, but unauthenticated requests can reach ACL evaluation instead of receiving an immediate 401 response. Only additional unusual proxy-header or ACL misconfiguration is documented as allowing requests to proceed into path and file-content handling.
- CVE-2026-62664Medium
FileRise prior to 3.19.0 does not reject dot-dot path segments in the folderName string before FolderModel::createFolder() constructs and creates the destination. An authenticated low-privileged user with a valid CSRF token and create or owner permission on the parent can submit traversal segments to POST /api/folder/createFolder.php and create directories outside UPLOAD_DIR.
- CVE-2026-61843High
Prior to 3.18.0, FileRise upload-enabled shared-folder and upload-only links do not reject a destination filename that already exists. An unauthenticated visitor with a valid share token and password can upload a file with the same name and silently replace its content while the original uploader metadata remains. The same gap affects ordinary authenticated uploads via /api/upload/upload.php and authenticated upload-only users lacking edit authority.
- CVE-2026-57493Medium
FileRise prior to 3.16.0 stores the isAdmin flag in remember-me tokens and restores that stale value during automatic login instead of resolving the account's current role from users.txt. A user who was issued a token while an administrator can retain administrator access after demotion, and token rotation copies the stale privilege into each replacement token.
Original NVD description (English source)
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.18.0, FileRise flattens logical folder paths into metadata filenames by replacing separators and spaces with hyphens, so distinct folders such as team/docs and team-docs can share one metadata file. Because uploader metadata is used to authorize read_own and ownership-restricted edits, a low-privileged user who controls one colliding folder, knows the target basename, and already has read_own access to the target folder can alter the metadata used by that folder, make the victim file appear attacker-owned, read it, and modify it when edit-own permission is also available. This issue is fixed in version 3.18.0.
