CVE-2026-79771

Nokogiri before 1.19.3 Memory Leak via XSLT Transform

Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.

Nokogiri before 1.19.1 Unchecked Return Value canonicalize

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

CVE-2026-72636

Uncontrolled Recursion in Elasticsearch Wildcard Matching Leading to Denial of Service

Uncontrolled Recursion (CWE-674) in the Elasticsearch wildcard matching helper can lead to a denial of service via Excessive Allocation (CAPEC-130). The matcher used to resolve wildcard patterns against names is implemented recursively and had no bound on recursion depth or on the total number of match operations performed. A search request containing a wildcard pattern with a large number of wildcard groups, evaluated against a sufficiently long name, exhausts the thread stack. Elasticsearch treats a stack overflow as an unrecoverable condition and shuts the node down, so the request terminates the affected node rather than failing gracefully.

CVE-2026-75797

AI Engine 3.3.3 - 3.7.1 - Subscriber+ Arbitrary File Read via 'url' Parameter

The AI Engine WordPress plugin before 3.7.2 does not confine a caller-supplied URL when mapping it to a local filesystem path before reading the file and forwarding its contents to an external service, allowing users with a subscriber-level account to read arbitrary files from the server and exfiltrate them off-host. Reaching the issue at subscriber level requires a non-default public API feature to be enabled; otherwise the same issue is reachable by an administrator, which on multisite allows a non-super subsite administrator to read the network-shared configuration and its secrets.

AI Engine 3.4.0 - 3.7.1 - Unauthenticated Arbitrary AI Query Execution via Editor Assistant

The AI Engine WordPress plugin before 3.7.2 does not perform an authorisation check on one of its administration-only features, relying instead on a token it hands out to anonymous visitors, allowing unauthenticated attackers to run AI queries of their own choosing against the site owner's configured provider account.

CVE-2026-18431

Avada <= 7.16 and Fusion Builder <= 3.16 - Unauthenticated Remote Code Execution via Arbitrary File Write

The Avada theme for WordPress is vulnerable to Arbitrary File Write in all versions up to, and including, 7.16 when the Fusion Builder plugin is installed and active in versions up to, and including, 3.16. This is due to a chain of authorization and input validation weaknesses across the two components that makes it possible for unauthenticated attackers to write attacker-controlled files to the server. This can be used to create and execute arbitrary PHP files, resulting in remote code execution and complete site compromise. Successful exploitation requires both Avada and Fusion Builder to be installed and active, as well as certain administrator-authored content to be present.

CVE-2026-9668

SQL injection vulnerability in ZTE SCP product

With legitimate user credentials in hand, attackers can construct malicious SQL statements to bypass authentication logic and execute arbitrary database queries directly. This will consequently lead to slow database queries and expanded query coverage. This vulnerability features a low exploitation threshold, wide scope of impact, requires no external privilege escalation, and is classified as a high-priority fix.

Formidable Charts <= 2.0.1 - Unauthenticated Arbitrary File Read via 'frm_graph' Parameter

The Formidable Charts plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.0.1 via the 'frm_graph' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires Formidable Forms Lite, Formidable Forms Pro, and Formidable Charts to be active and requires the wp-content/uploads/frm-charts/ directory to exist, normally after an image-format chart is rendered.
