Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45343 exists.\n\nAffected product: Kovah LinkAce. 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-2026-45343/ (Markdown: https://insights.sbomify.com/CVE-2026-45343/index.md)","id":"CVE-2026-45343","markdown":"https://insights.sbomify.com/CVE-2026-45343/index.md","name":"CVE-2026-45343","record":{"aliases":["GHSA-jx4g-ph82-x9mm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"LinkAce link archive","requires_auth":"low_privilege","summary":"Stored XSS in LinkAce admin audit log allows attackers to hijack admin sessions via malicious OAuth display names.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"LinkAce is a self-hosted archive to collect website links. Prior to 2.5.6, LinkAce contains a stored cross-site scripting vulnerability that allows a low-privilege user to execute arbitrary JavaScript in an administrator's browser session. This affects instances configured with SSO/OAuth authentication, which is one of the supported authentication methods in LinkAce. An attacker who sets their OAuth display name to a malicious script and then creates an API token will plant a persistent XSS payload in the audit log. When any admin navigates to /system/audit, the payload executes in the admin's browser context. This enables session cookie theft, CSRF token exfiltration (exposed in the la-app-data meta tag), or any other action the admin can perform. This vulnerability is fixed in 2.5.6.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"LinkAce - Stored XSS via Unsanitized SSO User's Name Rendered in Admin Audit Log Allows Session Hijacking","id":"CVE-2026-45343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"LinkAce: Setup database password newline injection enables pre-auth RCE on uninitialized instances","id":"CVE-2026-45344"},"packages":[],"prev":{"headline":"LinkAce: IDOR in Update Policies Allows Any Authenticated User to Overwrite Other Users' Links, Lists, Tags, and Notes","id":"CVE-2026-45342"},"products":["LinkAce"],"published":"2026-05-28","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-30","vendors":["Kovah"]},"summary":"Stored XSS in LinkAce admin audit log allows attackers to hijack admin sessions via malicious OAuth display names.","url":"https://insights.sbomify.com/CVE-2026-45343/"}
