Summary
The WPGancio plugin for WordPress up to version 1.12 is vulnerable to Stored Cross-Site Scripting via the 'gancio-event' shortcode. Authenticated attackers with contributor-level access or higher can inject arbitrary scripts that execute when a user accesses the page.
Risk Assessment
The risk includes session hijacking, data theft, or malware distribution on the WordPress site.
Recommendation
Update the plugin to the latest version immediately and consider restricting contributor permissions if feasible.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
The WPGancio plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'gancio-event' shortcode in all versions up to, and including, 1.12 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
