{"id":"CVE-2026-41689","state":"PUBLISHED","title":"Wallos: Shared local webhook allowlist lets low-privilege users send arbitrary requests to allowlisted internal services","description":"Wallos is an open-source, self-hostable personal subscription tracker. In versions 4.8.4 and prior, the webhook notification feature reuses an administrator-configured local-target allowlist for every logged-in user. Any normal user can fully control a webhook URL, headers, and body, then use Wallos to send server-side requests to allowlisted internal automation services. When such a target exposes deployment or execution APIs, this can further enable adjacent-service RCE, but that downstream result is conditional on the target service. At time of publication, there are no publicly available patches.","publishedAt":"2026-05-07T13:53:12.952Z","updatedAt":"2026-05-07T14:43:47.455Z","severity":{"score":6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["ellite Wallos"],"affected":[{"vendor":"ellite","product":"Wallos","versions":[{"version":"<= 4.8.4","status":"affected"}]}],"references":["https://github.com/ellite/Wallos/security/advisories/GHSA-jx6w-832g-42wv"],"weaknesses":["CWE-863","CWE-918"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41689.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41689","state":"PUBLISHED","datePublished":"2026-05-07T13:53:12.952Z","dateUpdated":"2026-05-07T14:43:47.455Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-22T03:53:24.407Z"},"containers":{"cna":{"title":"Wallos: Shared local webhook allowlist lets low-privilege users send arbitrary requests to allowlisted internal services","descriptions":[{"lang":"en","value":"Wallos is an open-source, self-hostable personal subscription tracker.
