Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-73159 in the wild and no public exploit code.\n\nAffected product: MISP cti-transmute. 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-2026-73159/ (Markdown: https://insights.sbomify.com/CVE-2026-73159/index.md)","id":"CVE-2026-73159","markdown":"https://insights.sbomify.com/CVE-2026-73159/index.md","name":"CVE-2026-73159","record":{"aliases":["GHSA-3vx2-8r8r-pf7r"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP cti-transmute","requires_auth":"low_privilege","summary":"Attackers can inject malicious HTML via crafted tag icons, leading to script execution in admin browsers on the triage interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Affected versions of cti-transmute allow a tag's icon value to be stored and later interpolated into HTML through Vue's v-html.

When the affected tag was later rendered, including on the administrative triage interface, the payload could execute in the viewer's browser.\n\nThe patch mitigates the issue at multiple layers: v-html is replaced with Vue :class binding, mapIcon() now returns only a constrained FontAwesome class string, and the backend validates icons against the FontAwesome catalogue or a strict [a-z0-9-]{1,40} slug pattern before storing them.","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":"cti-transmute Stored XSS via Crafted Tag Icon on Admin Triage Interface","id":"CVE-2026-73159","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"cti-transmute Unauthenticated SSRF via Hostnames Resolving to Internal IP Addresses","id":"CVE-2026-73160"},"packages":[],"prev":{"headline":"cti-transmute Saved Graph Configuration Allows Stored Cross-Site Scripting via svgIcon","id":"CVE-2026-73158"},"products":["cti-transmute"],"published":"2026-08-11","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":"2026-08-11","vendors":["MISP"]},"summary":"Attackers can inject malicious HTML via crafted tag icons, leading to script execution in admin browsers on the triage interface.","url":"https://insights.sbomify.com/CVE-2026-73159/"}
