CyberChef’s pretty-recipe parser vulnerable to client-side ReDoS / CPU exhaustion when parsing a malformed #recipe= URL

CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.3.0, CyberChef's pretty-recipe parser in src/core/Utils.mjs can exhaust client-side CPU when a malformed #recipe= URL fragment containing a large number of unmatched quote characters reaches Utils.parseRecipeConfig(). The function synchronously applies a complex global regular expression that may perform heavy backtracking before rejecting the input, causing the victim's browser tab to freeze during startup for seconds or longer. No code execution, data exfiltration, or privilege escalation occurs. This issue is fixed in version 11.3.0.

CyberChef: Prototype pollution in Series Chart operation

CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.2.0, the Series Chart operation accepts __proto__ as a key while parsing user-supplied CSV, allowing prototype pollution that can be chained with operations such as Parse UDP to inject malicious JavaScript into HTML output. This issue is fixed in version 11.2.0.

Cross‑Site Scripting in CyberChef’s Base64 Offset Feature

GCHQ CyberChef before 11.0.0 allows XSS via Show Base64 offsets, as demonstrated by the /#recipe=Show_Base64_offsets('%3Cscript substring.

Stroom Authentication/Authorization Bypass when using AWS ALB

Stroom is a data processing, storage and analysis platform. A vulnerability exists starting in version 7.2-beta.53 and prior to versions 7.2.24, 7.3-beta.22, 7.4.4, and 7.5-beta.2 that allows authentication bypass to a Stroom system when configured with ALB and installed in a way that the application is accessible not through the ALB itself. This vulnerability may also allow for server-side request forgery which may lead to code execution or further privileges escalations when using the AWS metadata URL. This scenario assumes that Stroom must be configured to use ALB Authentication integration and the application is network accessible. The vulnerability has been fixed in versions 7.2.24, 7.3-beta.22, 7.4.4, and 7.5-beta.2.

CyberChef before 8.31.2 allows XSS in core/operations/TextEncodingBruteForce.mjs.

All versions of stroom:stroom-app before 5.5.12 and all versions of the 6.0.0 branch before 6.0.25 are affected by Cross-site Scripting. An attacker website is able to load the Stroom UI into a hidden iframe. Using that iframe, the attacker site can issue commands to the Stroom UI via an XSS vulnerability to take full control of the Stroom UI on behalf of the logged-in user.

Stroom version <5.4.5 contains a XML External Entity (XXE) vulnerability in XML Parser that can result in disclosure of confidential data, denial of service, server side request forgery, port scanning. This attack appear to be exploitable via Specially crafted XML file.
