Insufficient verification of data authenticity in the IronVNC client in Devolutions Remote Desktop Manager 2026.2.17.0 and earlier, 2026.1.24.0 and earlier, allows an on-path attacker to intercept and tamper with VNC sessions via automatic acceptance of the server's RSA key during RSA-AES authentication.

CVE-2026-755096.5 MED0.5%
——0joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption (JOSE) standards. Prior to version 1.7.3, JWTClaimsRegistry applies membership matching to list-valued iss and sub claims, allowing an array-valued iss that contains the expected issuer to pass an intended equality check and enabling issuer-validation bypass. This issue is fixed in version 1.7.3.2dCVE-2026-622046.6 MED0.0%
——0SiYuan versions before v3.7.4 fail to validate that packageName matches the downloaded package content in bazaar install endpoints. Attackers with same-origin access can overwrite existing trusted plugins by supplying mismatched packageName and repoURL parameters, achieving persistence across application restarts.5dCVE-2026-580026.5 MED3.6%
——1WWBN AVideo through commit 9c39d8c8b4c1f75540788d6b391740852ceb0732 contains an authorization bypass vulnerability in the Users_affiliations add.json.php endpoint that allows authenticated users to forge two-party consent records by supplying the counterparty's agreement timestamp. Attackers can create a forged affiliation with status='a' and then reassign video ownership to arbitrary users through the videoAddNew.json.php endpoint, which trusts the forged affiliation as an authorization term.3dCVE-2026-48106—5.1%
——2Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise's cluster replication receiver at `internal/cluster/replication/receiver.go` validates only the wire-format envelope (length, opcode) of inbound messages. The `MsgReplicateSync` payload itself is accepted without any application-layer authentication — no HMAC, no signature, no per-message nonce. The replication stream is protected at the transport layer by TLS / mTLS, but there is no protection against application-layer message tampering or replay once a peer is on the cluster network. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit replication logs for unexpected `MsgReplicateSync` traffic, and/or disable cluster mode until the fix is available.6dCVE-2026-48105—6.4%
——2Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise's Raft FSM (`internal/cluster/raft/fsm.go:applyRegisterFile`) accepts attacker-chosen file paths in manifest-registration proposals without validating them against the configured storage backend. The only check is that the path is non-empty. There is no parent-traversal (`..`) rejection, no allowlist of legitimate prefixes, no scheme restriction (`s3://` vs local), and no length bound. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit the cluster manifest for unexpected paths (any path not matching the configured storage backend root is suspect), and/or disable cluster mode until the fix is available.3dCVE-2026-166505.3 MED2.4%
——1The Charitable WordPress plugin before 1.8.12 does not verify the authenticity of incoming Square payment webhook events in a default configuration, allowing unauthenticated attackers to forge webhook notifications that mark donations as paid without any real payment.6d
