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.","evidence":"cve:CVE-2026-100371","products":[{"name":{"value":"InvoicePlane","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-100371","aliases":["CVE-2026-100371"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":8.7,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"HIGH","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"NONE"}}],"affected":[{"vendor":"InvoicePlane","product":"InvoicePlane","versions":[{"status":"affected","version":"= 1.7.2"}]}],"modified":"2026-09-29T13:51:08.087Z","provider":"cve","references":["https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-77hm-22wp-96wp","https://github.com/InvoicePlane/InvoicePlane/pull/1638","https://github.com/InvoicePlane/InvoicePlane/commit/8616fa45a61c1694b55bb9116e293269a0ced06a"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100371","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T13:50:48.186591Z"}}}],"references":[{"url":"https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-77hm-22wp-96wp","tags":["exploit"]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T13:51:08.087Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-28T20:15:17.155Z"}}},"related_cves":[{"value":"CVE-2026-100371","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3451,"next_before":3451}
