Wallos 0.9 is vulnerable to Cross Site Scripting (XSS) in all text-based input fields without proper validation, excluding those requiring specific formats like date fields.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.2, password reset tokens in Wallos never expire. The passwordresets table includes a createdat timestamp column, but the token validation logic never checks it. A password reset token remains valid indefinitely until it is used, allowing an attacker who intercepts a reset link at any point to use it days, weeks, or months later. This issue has been patched in version 4.7.2.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, Wallos endpoints/logos/search.php accepts HTTPPROXY and HTTPSPROXY environment variables without validation, enabling SSRF via proxy hijacking. The server performs DNS resolution on user-supplied search terms, which can be controlled by attackers to trigger outbound requests to arbitrary domains. This issue has been patched in version 4.7.0.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the patch introduced in commit e8a513591 (CVE-2026-30840) added SSRF protection to notification test endpoints but left three additional attack surfaces unprotected: the AI Ollama host parameter, the AI recommendations endpoint, and the notification cron job. An authenticated user can reach internal network services, cloud metadata endpoints (AWS IMDSv1, GCP, Azure IMDS), or localhost-bound services by supplying a crafted URL to any of these endpoints. This issue has been patched in version 4.7.0.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the SSRF fix applied in version 4.6.2 for CVE-2026-30839 and CVE-2026-30840 is incomplete. The validatewebhookurlforssrf() protection was added to the test notification endpoints but not to the corresponding save endpoints. An authenticated user can save an internal/private IP address as a notification URL, and when the cron job sendnotifications.php executes, the request is sent to the internal IP without any SSRF validation. This issue has been patched in version 4.7.0.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, a stored cross-site scripting (XSS) vulnerability in the payment method rename endpoint allows any authenticated user to inject arbitrary JavaScript that executes when any user visits the Settings, Subscriptions, or Statistics pages. Combined with the walloslogin authentication cookie lacking the HttpOnly flag, this enables full session hijacking. This issue has been patched in version 4.7.0.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, the url parameter can be used to retrieve local system files. This issue has been patched in version 4.6.2.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, testwebhooknotifications.php does not validate the target URL against private/reserved IP ranges, enabling full-read SSRF. The server response is returned to the caller. This issue has been patched in version 4.6.2.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, there is a server-side request forgery vulnerability in notification testers. This issue has been patched in version 4.6.2.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, passwordreset.php outputs $GET["token"] and $GET["email"] directly into HTML input value attributes using <?= $token ?> and <?= $email ?> without calling htmlspecialchars(). This allows reflected XSS by breaking out of the attribute context. This issue has been patched in version 4.6.2.

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, Wallos allows an authenticated user to delete avatar files uploaded by other users. The avatar deletion endpoint does not verify that the requested avatar belongs to the current user. As a result, any authenticated user who knows or can discover another user's uploaded avatar filename can delete that file. This issue has been patched in version 4.6.2.

Wallos is an open-source, self-hostable personal subscription tracker. Versions 4.6.0 and below contain a Server-Side Request Forgery (SSRF) vulnerability in the subscription and payment logo/icon upload functionality. The application validates the IP address of the provided URL before making the request, but allows HTTP redirects (CURLOPTFOLLOWLOCATION = true), enabling an attacker to bypass the IP validation and access internal resources, including cloud instance metadata endpoints. The getLogoFromUrl() function validates the URL by resolving the hostname and checking if the resulting IP is in a private or reserved range using FILTERFLAGNOPRIVRANGE | FILTERFLAGNORESRANGE. However, the subsequent cURL request is configured with CURLOPTFOLLOWLOCATION = true and CURLOPTMAXREDIRS = 3, which means the request will follow HTTP redirects without re-validating the destination IP. This issue has been fixed in version 4.6.1.

Wallos before 1.15.3 is vulnerable to SQL Injection via the category and payment parameters to /subscriptions/get.php.

Wallos <= 2.38.2 has a file upload vulnerability in the restore backup function, which allows authenticated users to restore backups by uploading a ZIP file. The contents of the ZIP file are extracted on the server. This functionality enables an authenticated attacker (being an administrator is not required) to upload malicious files to the server. Once a web shell is installed, the attacker gains the ability to execute arbitrary commands.

Wallos <=2.38.2 has a file upload vulnerability in the restore database function, which allows unauthenticated users to restore database by uploading a ZIP file. The contents of the ZIP file are extracted on the server. This functionality enables an unauthenticated attacker to upload malicious files to the server. Once a web shell is installed, the attacker gains the ability to execute arbitrary commands.

Cross Site Scripting vulnerability in Wallos v.2.41.0 allows a remote attacker to execute arbitrary code via the profile picture function.
