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-2026-73524 in the wild and no public exploit code.\n\nAffected product: cypht-org cypht. 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-2026-73524/ (Markdown: https://insights.sbomify.com/CVE-2026-73524/index.md)","id":"CVE-2026-73524","markdown":"https://insights.sbomify.com/CVE-2026-73524/index.md","name":"CVE-2026-73524","record":{"aliases":["GHSA-r7q3-25g3-96cc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cypht webmail client","requires_auth":"none","summary":"Remote attackers can execute arbitrary scripts in victims' browsers via malicious FROM headers in Cypht's contacts module.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/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":"Cypht before 2.12.2 contains a cross-site scripting vulnerability in the contacts module that allows remote attackers to execute arbitrary script content by embedding malicious payloads within angle brackets in the FROM email header.
