An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-77506 in the wild and no public exploit code.\n\nAffected product: Znuny. 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-2026-77506/ (Markdown: https://insights.sbomify.com/CVE-2026-77506/index.md)","id":"CVE-2026-77506","markdown":"https://insights.sbomify.com/CVE-2026-77506/index.md","name":"CVE-2026-77506","record":{"aliases":["DEBIAN-CVE-2026-77506","GHSA-4mvf-wmjf-gpfv","UBUNTU-CVE-2026-77506"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Znuny ticket system","requires_auth":"high_privilege","summary":"An attacker can inject malicious scripts via the AgentTicketEmailResend template in Znuny, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Znuny before LTS 6.5.22 allows AgentTicketEmailResend template XSS.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cross-site scripting in Znuny","id":"CVE-2026-77506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Weblate: Object-scoped RSS feeds disclose private change history to unauthorized users","id":"CVE-2026-77507"},"packages":[],"prev":{"headline":"Windows DNS Server Remote Code Execution Vulnerability","id":"CVE-2026-77505"},"products":["Znuny"],"published":"2026-08-20","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":"2026-08-25","vendors":["Znuny"]},"summary":"An attacker can inject malicious scripts via the AgentTicketEmailResend template in Znuny, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2026-77506/"}
