HighCVSS 8.1Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
RabbitMQ to broker wiadomości i strumieniowania. W wersjach od 4.2.0 do przed 4.2.4, wtyczka MQTT RabbitMQ umożliwia autoryzację na poziomie tematów przy użyciu wyrażeń regularnych z podstawieniem zmiennych, co pozwala na obejście autoryzacji przez uwierzytelnionego użytkownika MQTT.
Risk Assessment
Podatność ta pozwala na nieautoryzowany dostęp do tematów, co może prowadzić do ujawnienia danych lub nieautoryzowanego działania w systemie. Organizacje mogą być narażone na ataki, które wykorzystują tę lukę do manipulacji danymi.
Recommendation
Zaleca się aktualizację RabbitMQ do wersji 4.2.4 lub 4.3.0, aby usunąć tę podatność. Dodatkowo, warto przeanalizować i dostosować polityki autoryzacji w celu zwiększenia bezpieczeństwa.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
- CVE-2026-124490Critical
OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
Original NVD description (English source)
RabbitMQ is a messaging and streaming broker. From 4.2.0 to before 4.2.4, RabbitMQ's MQTT plugin allows for topic-level authorization using regular expressions with variable substitution. Administrators can create patterns such as ^{client_id}-sensors$ to restrict user access to topics that include their client ID. However, the client_id is provided by the user in the MQTT CONNECT packet and is inserted into the regex pattern without escaping special regex characters. This flaw enables an authenticated MQTT user to inject regex operators to bypass authorization. This vulnerability is fixed in 4.2.4 and 4.3.0.
