CVE-2024-41655 2026-04-15 7.5 High
TF2 Item Format helps users format TF2 items to the community standards. Versions of `tf2-item-format` since at least `4.2.6` and prior to `5.9.14` are vulnerable to a Regular Expression Denial of Service (ReDoS) attack when parsing crafted user input. This vulnerability can be exploited by an attacker to perform DoS attacks on any service that uses any `tf2-item-format` to parse user input. Version `5.9.14` contains a fix for the issue.
CVE-2024-41128 1 Rails 1 Rails 2026-04-15 3.7 Low
Action Pack is a framework for handling and responding to web requests. Starting in version 3.1.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in the query parameter filtering routines of Action Dispatch. Carefully crafted query parameters can cause query parameter filtering to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to version 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. One may use Ruby 3.2 as a workaround. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.
CVE-2024-39249 1 Redhat 4 Advanced Cluster Security, Openshift Data Foundation, Rhdh and 1 more 2026-04-15 7.5 High
Async <= 2.6.4 and <= 3.2.5 are vulnerable to ReDoS (Regular Expression Denial of Service) while parsing function in autoinject function. NOTE: this is disputed by the supplier because there is no realistic threat model: regular expressions are not used with untrusted input.
CVE-2024-38809 2 Redhat, Vmware 2 Apache Camel Spring Boot, Spring Framework 2026-04-15 5.3 Medium
Applications that parse ETags from "If-Match" or "If-None-Match" request headers are vulnerable to DoS attack. Users of affected versions should upgrade to the corresponding fixed version. Users of older, unsupported versions could enforce a size limit on "If-Match" and "If-None-Match" headers, e.g. through a Filter.
CVE-2024-22363 2026-04-15 7.5 High
SheetJS Community Edition before 0.20.2 is vulnerable.to Regular Expression Denial of Service (ReDoS).
CVE-2024-21538 2 Cross-spawn, Redhat 12 Cross-spawn, Advanced Cluster Security, Discovery and 9 more 2026-04-15 7.5 High
Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.
CVE-2020-26306 1 Benhmoore 1 Knwl 2026-04-15 N/A
Knwl.js is a Javascript library that parses through text for dates, times, phone numbers, emails, places, and more. Versions 1.0.2 and prior contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). As of time of publication, no known patches are available.
CVE-2020-26310 1 Blowsie 1 Pure Javascript Html5 Parser 2026-04-15 N/A
Validate.js provides a declarative way of validating javascript objects. All versions as of 30 November 2020 contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). As of time of publication, it is unknown if any patches are available.
CVE-2025-9670 2026-04-15 5.3 Medium
A security flaw has been discovered in mixmark-io turndown up to 7.2.1. This affects an unknown function of the file src/commonmark-rules.js. Performing manipulation results in inefficient regular expression complexity. It is possible to initiate the attack remotely. The exploit has been released to the public and may be exploited.
CVE-2025-58451 2026-04-15 N/A
Cattown is a JavaScript markdown parser. Versions prior to 1.0.2 used regular expressions with inefficient, potentially exponential worst-case complexity. This could cause excessive CPU usage due to excessive backtracking on crafted inputs. In turn, the excessive CPU usage could lead to resource exhaustion, where processing malicious inputs could cause high CPU or memory usage, potentially leading to denial of service. Version 1.0.2 contains a patch. Additionally, users should review and restrict input sources if untrusted inputs are processed.
CVE-2020-26309 1 Ftonato 1 Nope-validator 2026-04-15 N/A
Validate.js provides a declarative way of validating javascript objects. Versions 0.11.3 and prior contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). As of time of publication, it is unknown if any patches are available.
CVE-2020-26307 1 Kates 1 Html2markdown 2026-04-15 N/A
HTML2Markdown is a Javascript implementation for converting HTML to Markdown text. All available versions contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). As of time of publication, no known patches are available.
CVE-2024-45338 1 Redhat 27 Acm, Advanced Cluster Security, Ceph Storage and 24 more 2026-04-15 5.3 Medium
An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.
CVE-2025-7579 2026-04-15 4.3 Medium
A vulnerability was found in chinese-poetry 0.1. It has been rated as problematic. This issue affects some unknown processing of the file rank/server.js. The manipulation leads to inefficient regular expression complexity. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
CVE-2024-47889 1 Rubyonrails 1 Rails 2026-04-15 3.7 Low
Action Mailer is a framework for designing email service layers. Starting in version 3.0.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in the block_format helper in Action Mailer. Carefully crafted text can cause the block_format helper to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. As a workaround, users can avoid calling the `block_format` helper or upgrade to Ruby 3.2. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 requires Ruby 3.2 or greater so is unaffected.
CVE-2024-7779 1 Danswer-ai 1 Danswer 2026-04-15 N/A
A vulnerability in danswer-ai/danswer version 1 allows an attacker to perform a Regular Expression Denial of Service (ReDoS) by manipulating regular expressions. This can significantly slow down the application's response time and potentially render it completely unusable.
CVE-2025-54364 1 Microsoft 1 Knack 2026-04-15 N/A
Microsoft Knack 0.12.0 allows Regular expression Denial of Service (ReDoS) in the knack.introspection module. option_descriptions employs an inefficient regular expression pattern: "\s(:param)\s+(.+?)\s:(.*)" that is susceptible to catastrophic backtracking when processing crafted docstrings containing a large volume of whitespace without a terminating colon. An attacker who can control or inject docstring content into affected applications can trigger excessive CPU consumption. This software is used by Azure CLI.
CVE-2025-6998 1 Janeczku 1 Calibre-web 2026-04-15 N/A
ReDoS in strip_whitespaces() function in cps/string_helper.py in Calibre Web and Autocaliweb allows unauthenticated remote attackers to cause denial of service via specially crafted username parameter that triggers catastrophic backtracking during login. This issue affects Calibre Web: 0.6.24 (Nicolette); Autocaliweb: from 0.7.0 before 0.7.1.
CVE-2024-52524 1 Giskard-ai 1 Giskard 2026-04-15 N/A
Giskard is an evaluation and testing framework for AI systems. A Remote Code Execution (ReDoS) vulnerability was discovered in Giskard component by the GitHub Security Lab team. When processing datasets with specific text patterns with Giskard detectors, this vulnerability could trigger exponential regex evaluation times, potentially leading to denial of service. Giskard versions prior to 2.15.5 are affected.
CVE-2024-52798 2 Pillarjs, Redhat 8 Path-to-regexp, Apache Camel Hawtio, Discovery and 5 more 2026-04-15 5.3 Medium
path-to-regexp turns path strings into a regular expressions. In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance. The regular expression that is vulnerable to backtracking can be generated in the 0.1.x release of path-to-regexp. Upgrade to 0.1.12. This vulnerability exists because of an incomplete fix for CVE-2024-45296.
