An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-5301 in the wild and no public exploit code.\n\nAffected product: coolercontrol-ui. 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-2026-5301/ (Markdown: https://insights.sbomify.com/CVE-2026-5301/index.md)","id":"CVE-2026-5301","markdown":"https://insights.sbomify.com/CVE-2026-5301/index.md","name":"CVE-2026-5301","record":{"aliases":["GHSA-6vr8-827j-mg8v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CoolerControl UI","requires_auth":"none","summary":"Unauthenticated attackers can execute malicious JavaScript via poisoned log entries in the CoolerControl UI, potentially taking over the service.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"coolercontrold","vendor":"coolercontrol"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Stored XSS in log viewer in CoolerControl/coolercontrol-ui \u003c4.0.0 allows unauthenticated attackers to take over the service via malicious JavaScript in poisoned log entries","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":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in coolercontrol-ui","id":"CVE-2026-5301","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Permissive Cross-domain Policy with Untrusted Domains in coolercontrold","id":"CVE-2026-5302"},"packages":[],"prev":{"headline":"Missing Authentication for Critical Function in coolercontrold","id":"CVE-2026-5300"},"products":["coolercontrol-ui"],"published":"2026-04-08","related":[{"cvss_score":8.2,"headline":"Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coolercontrold","id":"CVE-2026-5208","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":6.3,"headline":"Permissive Cross-domain Policy with Untrusted Domains in coolercontrold","id":"CVE-2026-5302","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":5.9,"headline":"Missing Authentication for Critical Function in coolercontrold","id":"CVE-2026-5300","kev_date_added":null,"published":"2026-04-08"}],"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":"2026-04-08","vendors":["CoolerControl"]},"summary":"Unauthenticated attackers can execute malicious JavaScript via poisoned log entries in the CoolerControl UI, potentially taking over the service.","url":"https://insights.sbomify.com/CVE-2026-5301/"}
