CVE-2026-45296 HIGH PATCH This Week

Cross-tenant data exposure in OpenReplay self-hosted session replay suite (versions prior to 1.26.0) allows an attacker holding any valid API key for their own tenant to enumerate sessions and retrieve sensitive session event data belonging to other tenants. The flaw stems from app_apikey routes in the Python API that validate the API key and the existence of a projectKey independently, but never confirm the two belong to the same tenant. No public exploit identified at time of analysis, though the trivial nature of the abuse (substituting a browser-visible projectKey) makes weaponization straightforward.

{id}/pin endpoint, where the server returns a 403 Forbidden response but the targeted record is already persistently modified. A publicly available exploit exists; this vulnerability is not confirmed actively exploited per CISA KEV, and impact is constrained to unauthorized data integrity modification without confidentiality or availability consequences.

Unauthenticated refund abuse in the Eupago Gateway for WooCommerce WordPress plugin before 4.7.2 lets remote attackers trigger refunds on arbitrary WooCommerce orders using the merchant's own payment gateway credentials, and for certain payment methods divert the refunded funds to an attacker-controlled bank account. The CVSS 8.6 score reflects the network-reachable, no-auth, no-interaction attack path against a financial workflow; publicly available exploit code exists per WPScan, though there is no public exploit identified at time of analysis confirming active exploitation in CISA KEV.

CVE-2026-32995 HIGH PATCH This Week

Cross-room message disclosure in Rocket.Chat allows any authenticated DDP user to read arbitrary messages - including those in private channels, direct messages, and E2EE rooms - by invoking the autoTranslate.translateMessage Meteor method with a target message ID. The flaw stems from missing access control and identity checks in the server-side method handler, with an upstream fix merged in PR #40528. No public exploit identified at time of analysis, though the trivial DDP call pattern makes weaponization straightforward.

CVE-2026-46416 MEDIUM This Month

Cross-connection response leakage in Microsoft UFO's WebSocket layer allows an authenticated low-privileged user to receive protocol responses intended for a different authenticated session. The flaw stems from a singleton UFOWebSocketHandler design where per-connection state is stored in shared mutable instance fields, causing each new connection to overwrite the previous connection's protocol object reference. No public exploit or CISA KEV listing exists at time of analysis, but the attack complexity is low and exploitation requires only standard authenticated access to the same UFO instance.

CVE-2026-47269 HIGH PATCH This Week

Authentication-context bypass in pam_usb before 0.9.0 lets a person holding an enrolled USB device authenticate over SSH while the module's deny_remote protection wrongly classifies the connection as a local terminal session. The root cause is an incomplete check of the utmpx ut_addr_v6 field that misreads IPv4-mapped IPv6 addresses (::ffff:x.x.x.x) as having no remote address, which is the normal way Debian and Ubuntu record incoming IPv4 SSH connections when sshd listens on the IPv6 wildcard. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV, but the operation needed to trigger it is trivial once the operator possesses a registered token.

CVE-2026-1933 HIGH This Week

Access control bypass in Samba allows authenticated SMB users who hold write permissions on the underlying filesystem to create or delete NTFS-style reparse point metadata on shares configured with 'read only = yes', defeating the read-only intent of the export. Because the necessary access checks are missing at the SMB layer, an attacker can change how files behave when accessed over SMB - for example, converting a regular file into a symbolic link or another reparse-point type - yielding an integrity and availability impact (CVSS 7.1). There is no public exploit identified at time of analysis, and CISA's SSVC framework rates exploitation as 'none', non-automatable, with partial technical impact.

CVE-2026-48906 CRITICAL Act Now

Arbitrary file deletion in the Novarain/Tassos Framework system plugin (plg_system_nrframework) and the suite of Tassos.gr Joomla extensions that bundle it lets remote unauthenticated attackers delete arbitrary files on affected sites. The CVSS 4.0 vector (PR:N/UI:N) and the 'Authentication Bypass' tag indicate no credentials or interaction are needed, and the high integrity/availability impact reflects that deleting core files such as Joomla's configuration.php can lead to denial of service or site takeover. There is no public exploit identified at time of analysis, and EPSS is low (0.07%, 21st percentile) with no CISA KEV listing, indicating no observed exploitation despite the critical 9.3 base score.

CVE-2026-41704 MEDIUM PATCH This Month

Arbitrary blobstore deletion in BOSH Director allows a compromised, high-privileged BOSH-managed VM to delete any object from the shared Director blobstore by injecting crafted NATS reply messages. All BOSH Director versions prior to v282.1.12 are affected, with the root cause being a complete absence of UUID-format validation, ownership checks, and namespace prefixing in ResourceManager before executing blobstore.delete(). An attacker leveraging this post-compromise path can corrupt or destroy deployment artifacts, compiled packages, and release binaries relied upon by dependent deployments, producing cascading availability failures across the BOSH environment. No public exploit or active exploitation has been identified at time of analysis; SSVC confirms exploitation status as none.
