CVE-2013-0269
HighSummary
Gem JSON w wersjach przed 1.5.5, 1.6.x przed 1.6.8 oraz 1.7.x przed 1.7.7 dla Ruby umożliwia zdalnym atakującym spowodowanie odmowy usługi (zużycie zasobów) lub obejście mechanizmu ochrony przed masowym przypisaniem poprzez spreparowany dokument JSON, który wywołuje tworzenie dowolnych symboli Ruby lub określonych obiektów wewnętrznych.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do przeprowadzenia ataków typu denial of service lub do obejścia zabezpieczeń aplikacji, co może prowadzić do nieautoryzowanego dostępu do danych lub zasobów systemowych.
Recommendation
Zaleca się aktualizację gemu JSON do wersji 1.5.5, 1.6.8 lub 1.7.7 lub nowszej, aby zniwelować ryzyko związane z tą podatnością.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress in all versions up to and including 1.2.3 is vulnerable to authorization bypass. This is due to the plugin not properly verifying that a user is authorized to perform an action. This allows unauthenticated attackers to modify the email address of arbitrary user accounts, including administrators, which can be leveraged to reset the account password and gain access.
- CVE-2026-12793Critical
The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress in all versions up to and including 3.6.2 is vulnerable to Privilege Escalation. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This allows unauthenticated attackers to create a new administrator-level user account.

- CVE-2026-61560Critical
`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.
Original NVD description (English source)
The JSON gem before 1.5.5, 1.6.x before 1.6.8, and 1.7.x before 1.7.7 for Ruby allows remote attackers to cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as demonstrated by conducting a SQL injection attack against Ruby on Rails, aka "Unsafe Object Creation Vulnerability."
