Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 5.0.0, the fix for CVE-2026-33407 (GHSA-hhjq-82f8-m6rc, "SSRF via HTTP Proxy Environment Variable") hardened endpoints/logos/search.php by disabling cURL proxying (CURLOPT_PROXY = '' + CURLOPT_NOPROXY = '*'). However, Wallos ships a second, near-identical, unauthenticated logo-image search endpoint - endpoints/payments/search.php - that was not given the same hardening. It still passes the HTTP_PROXY/HTTPS_PROXY environment variable straight into CURLOPT_PROXY. This issue has been patched in version 5.0.0.

AnalysisAI
Incomplete patch coverage in Wallos, the self-hosted subscription tracker, leaves a second unauthenticated logo-search endpoint (endpoints/payments/search.php) vulnerable to SSRF via HTTP proxy header injection - an oversight from the fix for CVE-2026-33407. Wallos prior to 5.0.0 passes the HTTP_PROXY/HTTPS_PROXY environment variable directly into cURL's CURLOPT_PROXY, allowing any unauthenticated network attacker to force the server's outbound HTTP requests through an attacker-controlled proxy. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required - `endpoints/payments/search.php` is explicitly described in the CVE as an unauthenticated endpoint, consistent with the CVSS PR:N metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N) accurately reflects the technical profile: the endpoint is network-reachable, requires no authentication, and no special server configuration is needed beyond a default Wallos deployment. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Wallos version 5.0.0, which applies the same proxy-disabling hardening to `endpoints/payments/search.php` that was previously applied to `endpoints/logos/search.php`. … Detailed patch versions, workarounds, and compensating controls in full report. |
