CVE-2026-77423 JLine: ReDoS in Built-in Less Viewer Search

JLine is a Java library for handling console input. From 3.0.0 until 3.30.15 and 4.3.1, the JLine built-in less viewer passes user-controlled search and display-filter patterns from getPatternboolean doDisplayPattern in builtins/src/main/java/org/jline/builtins/Less.java directly to Java's...

CVE-2026-77422

JLine is a Java library for handling console input. From 3.0.0 until 3.30.15 and 4.3.1, the JLine built-in grep command in builtins/src/main/java/org/jline/builtins/PosixCommands.java accepts a user-controlled regular expression in grep... and, unless line-regexp mode is used, automatically adds ...

CVE-2026-77421 JLine: ReDoS in Nano Editor Regex Search Mode

JLine is a Java library for handling console input. From 3.0.0 until 3.30.15 and 4.3.1, the JLine built-in nano editor's regex search mode passes a user-controlled search term from doSearchString text in builtins/src/main/java/org/jline/builtins/Nano.java to Java's backtracking regular expression...

GHSA-6XCW-7XM6-48C6 n8n: Expression Sandbox Escape via Shared Builtin Tampering and Code-Printer Injection Leads to Code Execution

Impact Two stages of expression code generation built source text by calling the global JSON.stringify at generation time: the compiler when printing synthetic string literals, and the isolate bridge when interpolating a timezone value into its per-evaluation wrapper. An expression that replaced...

GHSA-HW8V-XXG5-VVVX n8n: Expression Sandbox Escape via Class-Field Sanitizer Rebinding Can Lead to Code Execution

Impact The expression compiler's sanitizer resolved through a dynamically-scoped this, so a class field named sanitize rebound it and reached the Function constructor. On the backend, any expression author could run code in the n8n process; in the editor preview, a member's expression could run a...

CVE-2026-86083

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the legacy expression engine generated source text by calling the mutable global JSON.stringify while printing synthetic string literals and interpolating timezone data. An expression could replace...

CVE-2026-86083

n8n , an open-source workflow automation platform, is affected by a sandbox escape in its legacy expression engine.
