Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-51583 exists.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-51583/ (Markdown: https://insights.sbomify.com/CVE-2026-51583/index.md)","id":"CVE-2026-51583","markdown":"https://insights.sbomify.com/CVE-2026-51583/index.md","name":"CVE-2026-51583","record":{"aliases":["GHSA-qmhr-x227-7hgf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"usememos note-taking app","requires_auth":"low_privilege","summary":"An authenticated attacker can exploit a webhook validation flaw in usememos to perform Server-Side Request Forgery against internal network resources.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"An issue in usememos through v0.30.0 allows a remote authenticated attacker to perform Server-Side Request Forgery (SSRF) via the Webhook validation mechanism in internal/webhook/validate.go, by setting a webhook target to an internal address.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Server-side request forgery in n/a","id":"CVE-2026-51583","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in n/a","id":"CVE-2026-51584"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2026-51570"},"products":["n/a"],"published":"2026-08-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["n/a"]},"summary":"An authenticated attacker can exploit a webhook validation flaw in usememos to perform Server-Side Request Forgery against internal network resources.","url":"https://insights.sbomify.com/CVE-2026-51583/"}
