🚨 CVE-2026-62435
[This CNA information record relates to multiple CVEs; the
text explains which aspects/vulnerabilities correspond to which CVE.]

With the introduction of Grant Table v2 came the requirement to be able to
switch between versions. Switching from v1 to v2 reduces the number of
valid grant references, as a bigger shared entry structure is then needed
while the shared table doesn't change size. Switching from v2 back to v1
the status frames, which are separate in v2, go away.

Code holding, but intermediately dropping and then re-acquiring the grant
table lock, sometimes wrongly assumes that said properties wouldn't change
across the window in time where the lock is not being held.

The v1 -> v2 issue is CVE-2026-62435.

The v2 -> v1 issue is CVE-2026-62436.

🚨 CVE-2026-59878
Improper Input Validation vulnerability in Apache ActiveMQ AMQP, Apache ActiveMQ, Apache ActiveMQ All.

A remote unauthenticated peer that can reach an exposed AMQP NIO connector can trigger denial-of-service behavior by sending a frame size value. This cause the NIO threads to die and if done rapidly enough can lead to exhaustion of the NIO thread pool denying service to other connections.
This issue affects Apache ActiveMQ AMQP: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ All: before 5.19.9, from 6.0.0 before 6.2.8.

Users are recommended to upgrade to version 5.19.9, 6.2.8, or 6.3.0 which fixes the issue.

🚨 CVE-2026-61487
Improper Authorization vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.

An authenticated low-privilege user can bypass a per-destination
write ACL by sending to an ActiveMQ temporary composite destination whose physical name is a
comma-separated composite of real queues. This allows publishing messages to any of the destinations in the list without proper write ACL permissions because the authorization check is bypassed due to the composite destination being marked as temporary.
This issue affects Apache ActiveMQ Broker: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ All: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ: before 5.19.9, from 6.0.0 before 6.2.8.

schreibfaul1 ESP32-audioI2S v3.4.5 has an integer underflow vulnerability in the MP3Decoder::GetBits() function of the MP3 decoder due to unchecked bit reading operations. The lack of validation on the nBits parameter causes the cachedBits counter to underflow to negative values, leading to invalid bit manipulation, incorrect bitstream parsing, application crash, or arbitrary code execution via a specially crafted MP3 file.

🚨 CVE-2026-63727
Anchore Enterprise versions from 5.11.0 to 5.27.1 and 6.0.0 contain an improper privilege escalation vulnerability in the user management API. An authenticated attacker who is able to access the Anchore Enterprise API could issue an API call capable of modifying user permissions to gain access to additional resources and operations. It is not possible to grant the system-admin role, but a read only user could be granted write access. This issue is fixed in Anchore Enterprise 5.27.2 and 6.0.1.

🚨 CVE-2026-66713
Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component

 in Apache Software Foundation Apache Axis2/Java through 2.0.0 on Apache Tomcat

 (only when Tribes clustering is enabled, which is off by default) allows an

 unauthenticated remote attacker with network access to the clustering port to

 execute arbitrary code via a crafted serialized Java object delivered to the cluster

 channel and deserialized in

 org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Users are

 recommended to upgrade to version 2.0.1, which fixes this issue by removing the

🚨 CVE-2026-67174
Pivotick contains a DOM-based cross-site scripting vulnerability in its generic UI element resolution and icon-rendering utilities.

The tryResolveHTMLElement function treated any resolved string as HTML markup by assigning it to a <template> element through innerHTML. Strings derived from untrusted graph properties or custom rendering callbacks could therefore introduce arbitrary HTML or SVG elements into the live document. The vulnerable function was used by multiple UI components, including headers, property panels, extra panels, and tooltips.

Additionally, createIcon inserted caller-supplied svgIcon markup into a template without sanitization. An application integrating Pivotick and deriving icon markup from untrusted data could therefore expose a second script-execution path.

An unauthenticated attacker able to provide a crafted graph, property value, rendering result, or SVG icon could execute JavaScript in another user's browser when the affected content is displayed or interacted with. Successful exploitation could allow the attacker to access information available to the victim, manipulate graph data or application state, and perform actions with the victim's privileges.

The patch changes string rendering to use textContent, requiring callers to explicitly return an Element when HTML rendering is intended. It also sanitizes SVG icon markup before inserting it into the DOM.

🚨 CVE-2026-67178
MISP installation scripts generated an Apache HTTP virtual-host configuration containing an incorrectly formatted HTTP-to-HTTPS redirect:

Redirect permanent / https://misp.example

Apache’s Redirect directive appends any portion of the requested path that follows the matched prefix to the configured destination URL. Because the destination did not end with /, attacker-controlled path content was appended directly to the hostname rather than to its URL path.

For example, a request resembling:

http://misp.example/@attacker.example/

could result in a redirect resembling:

https://misp.example@attacker.example/

Under standard URL parsing, misp.example is interpreted as user information and attacker.example as the destination host. An unauthenticated remote attacker could therefore construct a URL hosted under the legitimate MISP domain that redirects users to an attacker-controlled website.

The vulnerability could be used for phishing, credential collection, or potentially disclosing sensitive query-string information preserved during the redirect. Exploitation requires a user to follow the crafted HTTP URL.

The fix adds the missing trailing slash to the redirect destination, ensuring that appended request data remains part of the path on the configured MISP host.



Existing installationsExisting MISP installations should review their Apache HTTP virtual-host configuration and ensure that the HTTPS redirect destination ends with a trailing slash:

Redirect permanent / https://misp.example/

After updating the configuration, validate it with apachectl configtest and reload or restart Apache for the change to take effect
