It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-95667 in the wild and no public exploit code.\n\nAffected product: MISP. 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-2026-95667/ (Markdown: https://insights.sbomify.com/CVE-2026-95667/index.md)","id":"CVE-2026-95667","markdown":"https://insights.sbomify.com/CVE-2026-95667/index.md","name":"CVE-2026-95667","record":{"aliases":["GHSA-qjpg-gmh7-3ch6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MISP threat sharing","requires_auth":"none","summary":"Local attackers can read world-readable installer logs to steal sensitive credentials, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The MISP installer scripts (for Debian 12, Debian 13, Ubuntu 24.04, and RHEL 9.4) create a log file at /var/log/misp_install.log and a named pipe (FIFO) at /var/log/misp_install.log.pipe to capture all installer output. The log captures highly sensitive data including the generated admin password, database passwords, GPG passphrase, and supervisor password. However, the log file was created by the tee command under the system default umask, resulting in world-readable permissions (typically 0644). Similarly, the FIFO was created with mkfifo without an explicit mode, also inheriting the default umask and remaining world-readable during the window before it was unlinked. \n\nAny local unprivileged user on the system could read the log file or the FIFO to obtain these credentials. \n\nAdditionally, the log file was not removed before creation, meaning a pre-existing symlink in /var/log could have been used to redirect the write to an arbitrary location.\n\nVersion affected: \u003c2.5.47","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":"MISP Installer Log and FIFO Created World-Readable, Exposing Sensitive Credentials","id":"CVE-2026-95667","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"No External Links \u003c= 5.2.0 - Unauthenticated Stored Cross-Site Scripting via Log URL via /goto/{base64} Redirect","id":"CVE-2026-95670"},"packages":[],"prev":{"headline":"Unbounded post ID array in the bulk reactions endpoint allows denial of service","id":"CVE-2026-95666"},"products":["MISP"],"published":"2026-09-22","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":"2026-09-22","vendors":["MISP"]},"summary":"Local attackers can read world-readable installer logs to steal sensitive credentials, potentially leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-95667/"}
