Description

Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, FW950.00 through FW950.H2, OP940.00 through OP940.a1, and OP940.00 - OP940.81 is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the BMC/FSP can exploit this vulnerability, allowing arbitrary code to be executed in the host firmware runtime, giving full control over the managed system, resulting in a confidentiality, integrity, and availability impact to the managed system.

CVE-2026-68900
Wekan is open source kanban built with Meteor. From 8.72 until 10.23, addBoardHTMLToZip() in client/lib/exportHTML.js read a card title and body through textContent, which decoded entity-encoded markup, and then interpolated titleText and allText into content.innerHTML in the exported index.html. A board member could store an entity-encoded event-handler payload in a card title that remained inert on the live board but was reparsed and executed when a recipient clicked the card in the downloaded HTML export, allowing the script to read and transmit all board data contained in that export, including content added after the attacker's membership was removed. Version 10.23 builds the modal with DOM nodes and assigns untrusted values through textContent. This issue is fixed in version 10.23.

CVE-2026-68899
Wekan is open source kanban built with Meteor. Prior to 9.90, isFileValid() in models/fileValidation.js used the Unix file command for content-based MIME detection, but detectMimeFromFile() silently returned undefined when that binary was unavailable and the validation fell back to the attacker-controlled fileObj.type supplied through server/routes/attachmentApi.js. On deployments with WITH_API=true and no file binary, an authenticated board member could label HTML containing JavaScript as image/png, bypass the dangerous MIME check, and store active content under the Wekan origin for execution when another user opened it. Version 9.90 adds looksLikeDangerousMarkup() to inspect file bytes and force dangerous-content scanning when MIME detection is unavailable. This issue is fixed in version 9.90.

CVE-2026-68561
Wekan is open source kanban built with Meteor. Prior to 9.89, the second Boards.allow({ update }) rule in server/permissions/boards.js called canUpdateBoardSort in server/lib/utils.js, which authorized any board member whenever fieldNames included sort. Because Meteor combines allow rules with OR semantics and applies the complete modifier, a comment-only or read-only member could send one Boards.update with $set values for sort, members, permission, and title, make themselves the sole board administrator, expose a private board, and evict the legitimate owner; the last-admin deny rule inspected only $pull and did not block a wholesale $set of members. Version 9.89 requires sort to be the only modified field and rejects $set member arrays that remove the last active administrator. This issue is fixed in version 9.89.

CVE-2026-68558
Wekan is open source kanban built with Meteor. From 8.36 until 9.74, the outgoing webhook Integration URL validator in models/integrations.js checked only the literal URL.hostname against regular expressions, so DNS names such as 169-254-169-254.nip.io passed that first-line check. The delivery path's fetchSafe guard already blocked the reported IPv4 destination, but its separate IPv4-only resolver and duplicated blocklist created inconsistent all-address-family enforcement and drift risk between input-time and connection-time validation. Version 9.74 makes server/lib/ssrfGuard.js resolve all addresses with `dns.lookup({ all: true })`, validate every result through the shared isIpBlocked logic, pin the connection, and block redirects. This issue is fixed in version 9.74.
