CVE-2026-11443
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.

Same Weakness Type(CWE-79)
Namespace attributes are not encoded correctly during HTML serialization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.
When ALLOW_INSECURE_RAW_TEXT is enabled, whitespace-variant closing tags (e.g., </style\t>) are not recognized by the sanitizer but accepted by browsers as valid end tags, allowing subsequent content to escape sanitization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.
A weakness has been identified in SourceCodester Inventory System 1.0. Affected by this issue is some unknown functionality of the file header.php. This manipulation causes cross site scripting. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. Multiple parameters might be affected.
VMware Cloud Foundation Operations contains multiple stored cross-site scripting vulnerabilities.A malicious actor with privileges to create policies, views or text-widgets may be able to inject scripts to perform administrative actions in VMware Cloud Foundation Operations.

A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files.
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.
