Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-89049 in the wild and no public exploit code.\n\nAffected product: AWS Amazon SSM Agent. 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-2026-89049/ (Markdown: https://insights.sbomify.com/CVE-2026-89049/index.md)","id":"CVE-2026-89049","markdown":"https://insights.sbomify.com/CVE-2026-89049/index.md","name":"CVE-2026-89049","record":{"aliases":["GHSA-w9jw-h72g-6hxc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"AWS Systems Manager Agent","requires_auth":"low_privilege","summary":"Authenticated users can bypass denylists via SSRF to steal IAM credentials from managed instances, requiring an upgrade to the SSM Agent.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-1289","name":"Improper Validation of Unsafe Equivalence in Input"}],"description":"A server-side request forgery issue due to improper validation of equivalent address representations in the port forwarding to remote hosts functionality in Amazon AWS Systems Manager Agent (SSM Agent) before 3.3.4851.0 on all platforms might allow an authenticated remote user to bypass the remote destination denylist and reach link-local endpoints, potentially obtaining the temporary IAM role credentials of a managed instance and acting with that role's permissions from outside the instance, via a crafted destination host value that uses an alternate representation of a denied link-local address.\n\nTo remediate this issue, users should upgrade to version 3.3.4851.0 or later.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Server-side request forgery in the Session Manager port forwarding functionality in AWS Systems Manager Agent","id":"CVE-2026-89049","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Quads Ads Manager for Google AdSense \u003c 3.0.5 - Subscriber+ Ad-Selling Payment Bypass via Unverified Success Return URL","id":"CVE-2026-89050"},"packages":[],"prev":{"headline":"Social Media Share Buttons \u0026 Social Sharing Icons \u003c= 3.0.1 - Reflected DOM-Based Cross-Site Scripting via URL","id":"CVE-2026-89047"},"products":["Amazon SSM Agent"],"published":"2026-09-10","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["AWS"]},"summary":"Authenticated users can bypass denylists via SSRF to steal IAM credentials from managed instances, requiring an upgrade to the SSM Agent.","url":"https://insights.sbomify.com/CVE-2026-89049/"}
