A malicious attacker can perform a Man‑in‑the‑Middle (MITM) attack by impersonating the opensolution.org server and serving arbitrary HTML or JavaScript at the plugin list endpoint. When a user accesses the plugin page, the malicious content is automatically fetched, rendered, and executed.\n\n\nThis issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.","aliases":[{"alias":"CVE-2026-33386"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-33386","reference_id":"","reference_type":"","scores":[{"value":"0.00032","scoring_system":"epss","scoring_elements":"0.1","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00032","scoring_system":"epss","scoring_elements":"0.09946","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00032","scoring_system":"epss","scoring_elements":"0.09995","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-33386"},{"reference_url":"https://cert.pl/posts/2026/05/CVE-2026-33384/","reference_id":"CVE-2026-33384","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-29T17:31:26Z/"}],"url":"https://cert.pl/posts/2026/05/CVE-2026-33384/"},{"reference_url":"https://opensolution.org/home.html","reference_id":"home.html","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-29T17:31:26Z/"}],"url":"https://opensolution.org/home.html"}],"weaknesses":[{"cwe_id":79,"name":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","description":"The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users."}],"exploits":[],"severity_range_score":"2.3 - 2.3","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-adh1-m12f-kqcm"}
