CVE-2026-91156
Description détaillée
Discourse is an open-source discussion platform. Prior to 2026.9.0, 2026.8.1, 2026.7.3, and 2026.1.9, MessageBus audience calculation could deliver messages from a read-restricted category chat channel to an authenticated user who could view the category but was not allowed to use Chat under the site's group restrictions. The publication path bounded events by category visibility without also enforcing Chat eligibility, exposing live and recent message content available in the MessageBus backlog. The issue does not permit retrieval of the channel's full history through the Chat API and does not permit message creation or modification. This issue is fixed in versions 2026.9.0, 2026.8.1, 2026.7.3, and 2026.1.9.

CVE-2026-92160
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileDownlink SendPartial range validation is vulnerable because the wrapping sum bypasses file-range validation, becomes m_endOffset, and leaves m_byteOffset greater than the wrapped end offset. When an existing source file is larger than the supplied startOffset and a caller able to issue SendPartial supplies a length whose U32 sum with that offset wraps, the first data-packet send reaches FW_ASSERT and aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.
CVE-2026-92159
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.
CVE-2026-92158
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::FpySequencer STORE directive stack write validation the bounds check adds attacker-controlled offset and size before memcpy, allowing integer wraparound to make an out-of-range destination appear valid. When a sequence-controlled STORE directive supplies a stack offset and size whose U32 sum wraps, memcpy can write outside the sequencer stack, causing memory corruption, denial of service, and potentially code execution. This issue is fixed in version 4.2.0.
