{"id":"GHSA-2cjv-6wg9-f4f3","summary":"Strapi Password Hashing is Missing Maximum Password Length Validation","details":"## Summary\n\nStrapi's password hashing implementation using bcryptjs lacks maximum password length validation. Since bcryptjs truncates passwords exceeding 72 bytes, this creates potential vulnerabilities such as authentication bypass and performance degradation.\n\n## POC\nCreate an admin user with a password exceeding 72 characters like 85,\nLog in using only the first 72 characters of the password.\nAuthentication is successful, confirming the issue.\n\nProposed Solution Based on  discussions:\n\nAdd a maximum password length validation (72 characters) during password creation and updates for both Admin and U&P users.\nTruncate passwords exceeding 72 bytes on the server before passing them to bcryptjs during login.\nOptionally, issue a warning to users with passwords longer than 72 bytes during login, informing them of truncation.\n\n## Impact\nThis issue affects all Strapi installations using bcryptjs for password hashing. Until resolved, it can lead to:\nAuthentication Bypass: Users may unknowingly set passwords exceeding 72 bytes, leading to truncated, predictable hashes.\nPerformance Issues: Excessively long passwords can degrade server performance.","aliases":["CVE-2025-25298"],"modified":"2025-11-27T09:11:22.621037Z","published":"2025-10-16T18:41:43Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2025-10-16T18:41:43Z","nvd_published_at":"2025-10-16T17:15:33Z","cwe_ids":["CWE-261"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/strapi/strapi/security/advisories/GHSA-2cjv-6wg9-f4f3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-25298"},{"type":"WEB","url":"https://github.com/strapi/strapi/commit/41f8cdf116f7f464dae7d591e52d88f7bfa4b7cb"},{"type":"PACKAGE","url":"https://github.com/strapi/strapi"}],"affected":[{"package":{"name":"@strapi/core","ecosystem":"npm","purl":"pkg:npm/%40strapi/core"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.10.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/10/GHSA-2cjv-6wg9-f4f3/GHSA-2cjv-6wg9-f4f3.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:N/VA:N/SC:N/SI:N/SA:N"}]}
