CVE-2026-48914
A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process.

Allegra downloadAttachment Cross-Site Scripting Authentication Bypass Vulnerability. This vulnerability allows remote attackers to execute arbitrary script on affected installations of Allegra. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the downloadAttachment method. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of arbitrary script. An attacker can leverage this vulnerability to execute script in the context of the current user. Was ZDI-CAN-28236.
Allegra exportReport Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Allegra. Authentication is required to exploit this vulnerability. The specific flaw exists within the exportReport method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose information in the context of the service account. Was ZDI-CAN-28208.
Capgo before 12.128.2 fails to delete previously uploaded profile images from backend storage when users replace or remove them. Attackers can access orphaned image files through previously generated URLs, allowing unauthorized retrieval of user-uploaded content.
OpenClaw before 2026.5.7 contains a hostname validation vulnerability in retry endpoint checks that allows matching hostname prefixes instead of exact hostnames. Attackers can exploit this by crafting a hostname prefix resembling a trusted host to send authentication material to untrusted endpoints.
OpenClaw before 2026.5.6 contains a configuration enforcement bypass vulnerability in Feishu dynamic-agent bindings that allows authenticated senders to create or update bindings without honoring configured config-write controls. Attackers can exploit this by leveraging the dynamic-agent binding feature to change sender-agent binding state beyond intended policy, potentially enabling unauthorized binding modifications.
