PYSEC-2026-2620 matrix-sydent and matrix-synapse Use Cryptographically Weak PRNG
An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID...
PYSEC-2026-1612 Synapse's invalid device keys degrade federation functionality
Impact Lack of validation for device keys in Synapse before 1.138.3 and in Synapse 1.139.0 allow an attacker registered on the victim homeserver to degrade federation functionality, unpredictably breaking outbound federation to other homeservers. Patches Patched in Synapse 1.138.3, 1.138.4,...
PYSEC-2026-1614 Synapse vulnerable to federation denial of service via malformed events
Impact A malicious server can craft events with a depth outside the integer range allowed by Canonical JSON. When such an event is received by Synapse version up to 1.127.0, it prevents it from federating with other servers. The vulnerability has been exploited in the wild. Patches Fixed in Synap...
PYSEC-2026-1610 Synapse Matrix has a partial room state leak via Sliding Sync
Impact The Sliding Sync feature on Synapse versions between 1.113.0rc1 and 1.120.0 can leak partial room state changes to users no longer in a room. Non-state events, like messages, are unaffected. Patches Synapse version 1.120.1 fixes the problem. Workarounds Disable Sliding Sync. References...
PYSEC-2026-1611 Synapse allows a a malformed invite to break the invitee's `/sync`
Impact Synapse versions before 1.120.1 fail to properly validate invites received over federation. This vulnerability allows a malicious server to send a specially crafted invite that disrupts the invited user's /sync functionality. Patches Synapse 1.120.1 rejects such invalid invites received ov...
PYSEC-2026-1613 Synapse allows unsupported content types to lead to memory exhaustion
Impact In Synapse before 1.120.1, multipart/form-data requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. Patches Synapse 1.120.1 resolves the issue by denying...
PYSEC-2026-1615 Synapse can be forced to thumbnail unexpected file formats, invoking external, potentially untrustworthy decoders
Impact In Synapse versions before 1.120.1, enabling the dynamicthumbnails option or processing a specially crafted request could trigger the decoding and thumbnail generation of uncommon image formats, potentially invoking external tools like Ghostscript for processing. This significantly expands...
Matrix Synapse DoS
Matrix Synapse before 0.28.1 is prone to a denial of service flaw where malicious events injected with depth = 263 - 1 render rooms unusable, related to federation/federationbase.py and handlers/message.py, as exploited in the wild in April 2018...
