CVE-2026-33285: Improper Input Validation

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's memoryLimit security mechanism can be completely bypassed by using reverse range expressions e.g., 100000000..1, allowing an attacker to allocate unlimited memory. Combined wit...

CVE-2026-4867: Inefficient Regular Expression Complexity

Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period .. For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two...

OpenClaw Denial of Service Vulnerability (CNVD-2026-15152)

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw has a denial of service hole that can be exploited by attackers to cause regular expression injection and denial of service...

PT-2026-28324

Name of the Vulnerable Software and Affected Versions Spring AI versions 1.0.0 through 1.0.4 and 1.1.0 through 1.1.3 Description Spring AI's SimpleVectorStore component contains a SpEL injection flaw. This occurs when user-provided input is used as a filter expression key. A malicious actor can...

CVE-2026-4926: Uncontrolled Resource Consumption

Impact: A bad regular expression is generated any time you have multiple sequential optional groups curly brace syntax, such as abc:z. The generated regex grows exponentially with the number of groups, causing denial of service. Patches: Fixed in version 8.4.0. Workarounds: Limit the number of...

CVE-2026-0967: Inefficient Regular Expression Complexity

A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...

CVE-2026-4923: Inefficient Regular Expression Complexity

Impact: When using multiple wildcards, combined with at least one parameter, a regular expression can be generated that is vulnerable to ReDoS. This backtracking vulnerability requires the second wildcard to be somewhere other than the end of the path. Unsafe examples: /foo-bar-:baz /a-:b-c-:d...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS when processing crafted extglob patterns. An attacker can cause excessive CPU consumption and block the event loop by supplying crafted extglob patterns that trigger catastrophic backtracking i...

Picomatch has a ReDoS vulnerability via extglob quantifiers

Impact picomatch is vulnerable to Regular Expression Denial of Service ReDoS when processing crafted extglob patterns. Certain patterns using extglob quantifiers such as + and , especially when combined with overlapping alternatives or nested extglobs, are compiled into regular expressions that c...

An attacker can cause excessive CPU consumption and block the event loop by supplying crafted extglob patterns that trigger catastrophic backtracking i...

The vulnerability of the Python Markdown library’s extensions, specifically pymdown-extensions, arises from the use of a regular expression “c” with inefficient computational complexity. This allows attackers to trigger a denial-of-service attack.

The vulnerability of the pymdown-extensions extension for the Python Markdown library is related to the use of a regular expression with inefficient computational complexity. Exploiting this vulnerability could allow an attacker to cause service interruptions remotely...

Allocation of Resources Without Limits or Throttling

Overview Scriban is a Scriban is a fast, powerful, safe and lightweight scripting language and engine for .NET, which was primarily developed for text templating with a compatibility mode for parsing liquid templates. Today, not only Scriban can be used in text templating scenarios, but also can ...

Allocation of Resources Without Limits or Throttling

Overview Scriban.Signed is a fast, powerful, safe and lightweight scripting language and engine for .NET, which was primarily developed for text templating with a compatibility mode for parsing liquid templates. Affected versions of this package are vulnerable to Allocation of Resources Without...

Scriban: Built-in operations bypass LoopLimit and delay cancellation, enabling Denial of Service

Summary Scriban's LoopLimit only applies to script loop statements, not to expensive iteration performed inside operators and builtins. An attacker can submit a single expression such as 1..1000000 | array.size and force large amounts of CPU work even when LoopLimit is set to a very small value...

Scriban has a Stack Overflow via Nested Array Initializers That Bypass the ExpressionDepthLimit Fix

Summary StackOverflowException via nested array initializers bypasses ExpressionDepthLimit fix GHSA-wgh7-7m3c-fx25 Details The recent fix for GHSA-wgh7-7m3c-fx25 uncontrolled recursion in parser added ExpressionDepthLimit defaulting to 250. However, deeply nested array initializers ... recurse...
