Summary
The Contact Form 7 with ChatWork plugin for WordPress in versions up to and including 1.1.0 is vulnerable to Stored Cross-Site Scripting via the 'api_token' and 'roomid' settings due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts that execute when a user visits the settings page. This only affects multi-site installations and installations where `unfiltered_html` has been disabled.
Risk Assessment
A site administrator may inadvertently execute a malicious script, potentially leading to session hijacking or further privilege escalation. The risk is limited to multi-site installations and those with `unfiltered_html` disabled.
Recommendation
Update the Contact Form 7 with ChatWork plugin to a version newer than 1.1.0 as soon as it becomes available, and consider enabling `unfiltered_html` for administrators if possible.

- CVE-2026-7826Critical
A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
The Contact Form 7 with ChatWork plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'api_token' and 'roomid' settings in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses the settings page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
