An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-86242 exists.\n\nAffected product: maximhq Bifrost. 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-2026-86242/ (Markdown: https://insights.sbomify.com/CVE-2026-86242/index.md)","id":"CVE-2026-86242","markdown":"https://insights.sbomify.com/CVE-2026-86242/index.md","name":"CVE-2026-86242","record":{"aliases":["GHSA-2qp8-4xgm-fw6g","GHSA-7g8f-4jrf-x782"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Bifrost HTTP transport","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution on dynamically linked Bifrost builds by uploading malicious plugins via HTTP paths when management authentication is disabled.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JFROG","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Bifrost HTTP transport before 2.0.0 accepts an enabled custom plugin whose path is an HTTP URL through unauthenticated POST /api/plugins when management authentication is disabled (the default, governance.auth_config.is_enabled=false). The shared-object loader treats an http-prefixed path as a download URL, writes the body to a temporary .so, and passes it to Go's plugin.Open. After a successful open, optional Init runs immediately with the supplied config as the Bifrost process user. On documented dynamically linked builds (DYNAMIC=1 / no static-link flags), which the vendor requires for custom Go plugins, plugin.Open is expected to succeed and this is unauthenticated remote code execution. On the published statically linked Docker image, plugin.Open fails with Dynamic loading not supported, so that build class is only server-side request forgery. Attack complexity is High because the attacker cannot force RCE on the default static image and a loadable plugin must match the host Go version, OS, architecture, and linkage. The 1.6.x HTTP transport line through 1.6.11 does not contain the fix.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-86242.yaml","stars":null,"title":"Bifrost \u003c 1.6.3 - Unauthenticated Remote Plugin URL Fetch"}],"tier":"weaponised"},"has_fix":false,"headline":"Unauthenticated RCE via Custom Plugin HTTP Path on Dynamically Linked Builds","id":"CVE-2026-86242","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Apache Tomcat Native: DoS via TLS handshake","id":"CVE-2026-86243"},"packages":[],"prev":{"headline":"liufee FeehiCMS Cookie Validation main-local.php hard-coded key","id":"CVE-2026-86241"},"products":["Bifrost"],"published":"2026-09-06","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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-08","vendors":["maximhq"]},"summary":"Unauthenticated attackers can achieve remote code execution on dynamically linked Bifrost builds by uploading malicious plugins via HTTP paths when management authentication is disabled.","url":"https://insights.sbomify.com/CVE-2026-86242/"}
