{"id":"CVE-2026-92298","summary":"EspoCRM through 10.0.8 Weak Token Generation via rand()","details":"EspoCRM through 10.0.8 uses PHP's rand() function to generate tokens for lead-capture opt-in, event invitation, and campaign URLs instead of a cryptographically secure generator. Remote unauthenticated attackers can guess these roughly 31-bit tokens to confirm opt-ins, accept or decline event invitations on behalf of other contacts, and access event details.","modified":"2026-09-19T03:30:52.704894641Z","published":"2026-09-16T01:57:46.309Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-338"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92298.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92298.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92298"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/espocrm-through-10.0.8-weak-token-generation-via-rand"},{"type":"FIX","url":"https://github.com/espocrm/espocrm/commit/8e5555c1ee0ed1e92a9ad54e62f735ac2c4051a1"},{"type":"PACKAGE","url":"https://github.com/espocrm/espocrm"},{"type":"ARTICLE","url":"https://gist.github.com/kazisabu/9e3109aab24245fde19b88f53f965e93"},{"type":"ARTICLE","url":"https://github.com/espocrm/espocrm/blob/10.0.8/application/Espo/Core/Utils/Util.php#L585-L590"},{"type":"ARTICLE","url":"https://github.com/espocrm/espocrm/blob/10.0.8/application/Espo/Repositories/UniqueId.php#L47"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/espocrm/espocrm","events":[{"introduced":"0"},{"fixed":"863109b2a8649b7724e0e6eb7039fcc3afdbe26c"},{"fixed":"8e5555c1ee0ed1e92a9ad54e62f735ac2c4051a1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"10.0.8"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["10.0.7","10.0.6","10.0.5","10.0.4","10.0.3","10.0.2","10.0.1","10.0.0","9.3.0","9.2.0","9.1.0","9.0.2","9.0.1","9.0.0","8.4.0","8.2.0","8.1.0","8.0.2","8.0.1","8.0.0","7.4.3","7.4.2","7.4.1","7.4.0","7.3.0","7.2.0","7.1.3","7.1.2","7.1.1","7.1.0","7.0.8","7.0.7","7.0.6","7.0.5","7.0.4","7.0.3","7.0.2","7.0.1","7.0.0","6.0.1","6.0.0","6.0.0-beta4","6.0.0-beta2","6.0.0-beta1","5.9.2","5.9.1","5.9.0","5.8.2","5.8.1","5.8.0","5.7.5","5.7.4","5.7.3","5.7.2","5.7.1","5.7.0","5.6.1","5.6.0","5.5.1","5.5.0","5.4.3","5.4.2","5.4.1","5.4.0","5.3.2","5.3.1","5.3.0","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2.0","5.1.2","5.1.1","5.1.0","5.0.1","5.0.0","4.8.0","4.7.0","4.6.0","4.5.0","4.4.0","4.3.0","4.3.0-beta.2","4.3.0-beta.1","4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.4","4.1.3","4.1.2","4.1.1","4.1.0","4.0.3","4.0.2","4.0.1","4.0.0","4.0.0-beta.4","4.0.0-beta.3","4.0.0-beta.2","4.0.0-beta.1","3.9.1","3.9.0","3.8.0","3.7.1","3.7.0","3.6.1","3.6.0","3.5.0","3.4.2","3.4.1","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0","2.9.0","2.8.1","2.8.0","2.6.0","2.5.2","2.5.1","2.5.0","2.4.0","2.3.0","2.0.1","1.2.0","1.1.2","1.1.1","1.1.0","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92298.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
