Summary
A deserialization vulnerability was found in the retrieval_lm component of AkariAsai self-rag up to commit 1fcdc420e48f50a7d7ab1ece5494221b93252e99, specifically in the Indexer.deserialize_from function of retrieval_lm/src/index.py. The attack can be launched remotely by manipulating the index_meta.faiss argument, and the exploit has been publicly disclosed.
Risk Assessment
The risk involves potential remote code execution or data integrity compromise, which could lead to system takeover or sensitive information leakage.
Recommendation
Immediately apply patches or update to the latest project version once available, and temporarily restrict access to the vulnerable component.

KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential; the JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, allowing the attacker to obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations.

A vulnerability in the Advanced Malware Protection (AMP) feature of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to write arbitrary files on the underlying operating system. It is due to improper handling of email attachments when the file reputation service is enabled; an attacker could send an email with a crafted attachment through an affected device, potentially allowing arbitrary file writes and command execution with root privileges.

A missing authentication vulnerability in Lantronix XPress-DR and XPress-DR-I (CoBos-family) firmware through 8.1.0.0 allows remote attackers to read and persistently overwrite device configuration by sending crafted frames to the unauthenticated UDP configuration protocol on port 30718. Attackers can send a type 0xF8 query to read live configuration data and a type 0xFD frame with exactly 0x78 body bytes to rewrite the device IP address and serial-channel forwarding records, causing changes to commit to EEPROM and persist across reboots. The XPress-DR product series reached end-of-life/end-of-support in February 2025.
