CVE-2024-47888 1 Rails 1 Rails 2026-04-15 3.7 Low
Action Text brings rich text content and editing to Rails. Starting in version 6.0.0 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 `plain_text_for_blockquote_node helper` in Action Text. Carefully crafted text can cause the `plain_text_for_blockquote_node` 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 `plain_text_for_blockquote_node` 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 depends on Ruby 3.2 or greater so is unaffected.
CVE-2024-47887 1 Rubyonrails 1 Rails 2026-04-15 3.7 Low
Action Pack is a framework for handling and responding to web requests. Starting in version 4.0.0 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 Action Controller's HTTP Token authentication. For applications using HTTP Token authentication via `authenticate_or_request_with_http_token` or similar, a carefully crafted header may cause header parsing 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. One may choose to 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-2024-41128 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-2024-36751 2026-04-15 6.5 Medium
An issue in parse-uri v1.0.9 allows attackers to cause a Regular expression Denial of Service (ReDoS) via a crafted URL.
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-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-2024-21503 2 Python Software Foundation, Redhat 2 Black, Ansible Automation Platform 2026-04-15 5.3 Medium
Versions of the package black before 24.3.0 are vulnerable to Regular Expression Denial of Service (ReDoS) via the lines_with_leading_tabs_expanded function in the strings.py file. An attacker could exploit this vulnerability by crafting a malicious input that causes a denial of service. Exploiting this vulnerability is possible when running Black on untrusted input, or if you habitually put thousands of leading tab characters in your docstrings.
CVE-2024-21539 1 Eslint 1 Rewrite 2026-04-15 7.5 High
Versions of the package @eslint/plugin-kit before 0.2.3 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 exploiting this vulnerability.
CVE-2025-54363 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. extract_full_summary_from_signature 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-2025-54364 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-2024-45813 1 Redhat 3 Acm, Multicluster Engine, Openshift Devspaces 2026-04-15 5.3 Medium
find-my-way is a fast, open source HTTP router, internally using a Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework independent. A bad regular expression is generated any time one has two parameters within a single segment, when adding a `-` at the end, like `/:a-:b-`. This may cause a denial of service in some instances. Users are advised to update to find-my-way v8.2.2 or v9.0.1. or subsequent versions. There are no known workarounds for this issue.
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-2025-2811 2026-04-15 5.7 Medium

It is recommended to upgrade the affected component.
CVE-2025-4690 1 Angularjs 1 Angularjs 2026-04-15 4.3 Medium
A regular expression used by AngularJS'  linky https://docs.angularjs.org/api/ngSanitize/filter/linky  filter to detect URLs in input text is vulnerable to super-linear runtime due to backtracking. With a large carefully-crafted input, this can cause a Regular expression Denial of Service (ReDoS) https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS  attack on the application. This issue affects all versions of AngularJS. Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see here https://docs.angularjs.org/misc/version-support-status .
CVE-2025-10990 1 Redhat 4 Rhel Satellite Client, Satellite, Satellite Capsule and 1 more 2026-04-15 7.5 High
