Attackers can manipulate the mail identifier value, such as reloadMailTypeId=mail-1, to retrieve the title and body of private messages belonging to other users, resulting in unauthorized disclosure of sensitive communications.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},{"score":7.1,"severity":"high","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":6.5,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1794608245443,"publishedAt":1794589362943,"references":[{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://www.akailabs.fr/blog/multiple-vulnerabilities-in-agora-project-26-5-2#cve-2026-63164-idor-in-reloadmailtypeid-allows-reading-and-exfiltration-of-other"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://www.agora-project.net/"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/omnispace-agora-project-idor-via-reloadmailtypeid-parameter"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.agora-project.net/"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.akailabs.fr/blog/multiple-vulnerabilities-in-agora-project-26-5-2#cve-2026-63164-idor-in-reloadmailtypeid-allows-reading-and-exfiltration-of-other"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/omnispace-agora-project-idor-via-reloadmailtypeid-parameter"}],"remediation":[],"revision":"46ff1de38f47182e73b40d461dcfe065973cbeca77ef8d7afcfe8252c7fec807","sources":[{"modifiedAt":1794604360343,"name":"CNA: VulnCheck","retrievedAt":1794607797270,"url":"https://www.cve.org/CVERecord?id=CVE-2026-63164"},{"modifiedAt":1794608245443,"name":"NVD","retrievedAt":1794615571100,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63164"}],"ssvc":{"assessedAt":1794604352921,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Omnispace Agora Project 26.10.0 IDOR via reloadMailTypeId Parameter","updatedAt":1794615571100}
