Descripción técnica

Kimai before 2.63.0 contains a business logic / improper authorization vulnerability in the team update API endpoint (PATCH /api/teams/{id}), which removes all existing team members before validating the submitted replacement member list. An authenticated teamlead (or other user) with permission to edit a team can submit a malformed members payload; although Kimai returns a validation error, the existing membership rows have already been deleted. This bypasses the dedicated member-removal endpoint's protection against removing teamleaders and can leave a team with no members or teamleaders, disrupting team-based access control.

——7Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, processPercentageRoyaltiesTransfer in core/kapp/accounts/accounts.go calls SubFromBalance after the split loop and after the royaltiesToPay <= 0 early return. computeSplitRoyalties rejects only when splitToPay > royaltiesToPay, so a valid PercentTransferPercentage = 10000 split consumes exactly 100 percent of the royalty pool, sets royaltiesToPay to zero, and returns before the source account is debited. The split recipient receives the full royaltyAmount while the sender pays nothing and the supply counter is not updated, allowing unbounded off-the-books inflation of the transferred KDA. A KDA owner must configure a TransferPercentage royalty with a 100 percent split, after which any holder's transfer of the asset triggers the mint; the sibling processFixedRoyaltiesTransfer path is not affected because it debits the source before distribution. This issue is fixed in version 1.7.19.5d CVE-2026-78618—

——6WatchGuard Dimension provides a client-side lock/unlock UI control for management changes. The server-side configuration endpoint does not enforce this lock/unlock workflow state, allowing an authenticated administrator to submit configuration changes directly to the endpoint without first completing the UI unlock step. This allows an authenticated read-write administrator session to bypass the intended editing workflow and overwrite configuration changes being made by another concurrent administrator session.8d CVE-2026-775083.5 BAJ

Prior to 2026.8, an authenticated user can change the account's primary email through PUT or PATCH requests to /api/users/{username}/ without verifying the new address, allowing a later team invitation for that address to be accepted without access to the intended recipient's mailbox.
