An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100265 in the wild and no public exploit code.\n\nAffected product: JetBrains Rider. 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-2026-100265/ (Markdown: https://insights.sbomify.com/CVE-2026-100265/index.md)","id":"CVE-2026-100265","markdown":"https://insights.sbomify.com/CVE-2026-100265/index.md","name":"CVE-2026-100265","record":{"aliases":["GHSA-f82x-3h7v-827j"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JetBrains Rider IDE","requires_auth":"none","summary":"Attackers can execute arbitrary code via auto-updated third-party skills in JetBrains Rider without user confirmation.","user_interaction":"not_required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"rider","vendor":"jetbrains"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"In JetBrains Rider before 2026.2.1 aI Assistant could auto-update third-party skills without user confirmation","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Supply chain in Rider","id":"CVE-2026-100265","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"supply_chain","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Hub","id":"CVE-2026-100266"},"packages":[],"prev":{"headline":"Information disclosure in YouTrack","id":"CVE-2026-100264"},"products":["Rider"],"published":"2026-09-30","related":[{"cvss_score":7.8,"headline":"Supply chain in n/a","id":"CVE-2019-14960","kev_date_added":null,"published":"2019-10-01"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2020-7906","kev_date_added":null,"published":"2020-01-30"},{"cvss_score":5.4,"headline":"Path traversal in Rider","id":"CVE-2025-43016","kev_date_added":null,"published":"2025-04-25"},{"cvss_score":4.1,"headline":"Security feature bypass in Rider","id":"CVE-2022-37396","kev_date_added":null,"published":"2022-08-03"},{"cvss_score":3.3,"headline":"Information disclosure in Rider","id":"CVE-2024-24939","kev_date_added":null,"published":"2024-02-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-30","vendors":["JetBrains"]},"summary":"Attackers can execute arbitrary code via auto-updated third-party skills in JetBrains Rider without user confirmation.","url":"https://insights.sbomify.com/CVE-2026-100265/"}
