Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-34476 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/apache/skywalking-mcp (Go): affected all versions; fixed in 0.2.0\n- github.com/apache/skywalking-mcp (Go): affected all versions; fixed in 0.2.0\n- github.com/apache/skywalking-mcp (Go): affected all versions; fixed in 0.2.0\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-2026-34476/ (Markdown: https://insights.sbomify.com/CVE-2026-34476/index.md)","id":"CVE-2026-34476","markdown":"https://insights.sbomify.com/CVE-2026-34476/index.md","name":"CVE-2026-34476","record":{"aliases":["GHSA-c4hg-6933-x62x","GO-2026-5310"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache SkyWalking MCP","requires_auth":"low_privilege","summary":"An attacker can exploit a Server-Side Request Forgery vulnerability in Apache SkyWalking MCP via the SW-URL header to access internal resources.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"skywalking_mcp","vendor":"apache"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-Side Request Forgery via SW-URL Header vulnerability in Apache SkyWalking MCP.\n\nThis issue affects Apache SkyWalking MCP: 0.1.0.\n\nUsers are recommended to upgrade to version 0.2.0, which fixes this issue.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache SkyWalking MCP: Server-Side Request Forgery via SW-URL Header in MCP Server","id":"CVE-2026-34476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Apache Log4j Core: `verifyHostName` attribute silently ignored in TLS configuration","id":"CVE-2026-34477"},"packages":[{"ecosystem":"Go","fixed":["0.2.0"],"introduced":["0"],"last_affected":[],"package":"github.com/apache/skywalking-mcp","purl":null,"source":"GHSA-c4hg-6933-x62x"},{"ecosystem":"Go","fixed":["0.2.0"],"introduced":["0"],"last_affected":[],"package":"github.com/apache/skywalking-mcp","purl":"pkg:golang/github.com/apache/skywalking-mcp","source":"GHSA-c4hg-6933-x62x"},{"ecosystem":"Go","fixed":["0.2.0"],"introduced":["0"],"last_affected":[],"package":"github.com/apache/skywalking-mcp","purl":"pkg:golang/github.com/apache/skywalking-mcp","source":"GO-2026-5310"}],"prev":{"headline":"Varnish Cache before 8.0.1 and Varnish Enterprise before 6.0.16r12, in certain unchecked req.url scenarios, mishandle URLs with a path of /","id":"CVE-2026-34475"},"products":["Apache SkyWalking MCP"],"published":"2026-04-13","related":[{"cvss_score":9.8,"headline":"Apache SkyWalking MCP: SSRF via set_skywalking_url Tool and GraphQL Expression Injection in MCP Server","id":"CVE-2026-34884","kev_date_added":null,"published":"2026-08-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-13","vendors":["Apache Software Foundation"]},"summary":"An attacker can exploit a Server-Side Request Forgery vulnerability in Apache SkyWalking MCP via the SW-URL header to access internal resources.","url":"https://insights.sbomify.com/CVE-2026-34476/"}
