In version 1.7.2, an authorization guard to Users::change_password(), was added to address a previous authorization flaw that allowed a secondary administrator (user_type=1, user_id != 1) to directly change the password of the primary administrator (user_id=1) through users/change_password/{id}. That remediation, however, protects only the direct password-change operation. It does not protect the identity attribute that password recovery actually trusts: user_email. Users::form() applies no equivalent object-level authorization check when editing the primary administrator's account, and user_email is not included in PROTECTED_FIELDS. A secondary administrator can therefore rewrite the primary administrator's email address, then drive the public password-recovery flow — which resolves the account by user_email — to receive the reset token and take over user_id=1. The result is an alternate attack path that achieves the same impact PR #1638 was intended to prevent: cross-administrator full account takeover of the primary administrator. This issue has been patched via commit 8616fa4.","categories":["Unclassified"],"product":"InvoicePlane","vendor":"InvoicePlane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100371","source_modified_at":"2026-09-29T13:51:08.087Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"InvoicePlane","vendor":"InvoicePlane","versions":[{"version":"= 1.7.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00276,"percentile":0.19026,"score_date":"2026-10-23"},"published_at":"2026-09-28T20:15:17.155Z","modified_at":"2026-09-29T13:51:08.087Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100371","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T13:51:08.087Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100371","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-77hm-22wp-96wp","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/InvoicePlane/InvoicePlane/pull/1638","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/InvoicePlane/InvoicePlane/commit/8616fa45a61c1694b55bb9116e293269a0ced06a","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-29T13:50:48.186591Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T13:51:08.087Z","content_hash":"358f1ab677946af8a22cf5acd63d7a5faaaa5c6a30836dee8e73862739f6cedc"}}
