CVE-2023-3446 1 Openssl 1 Openssl 2025-04-23 N/A 5.3 MEDIUM
Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs various checks on DH parameters. One of those checks confirms that the modulus ('p' parameter) is not too large. Trying to use a very large modulus is slow and OpenSSL will not normally use a modulus which is over 10,000 bits in length. However the DH_check() function checks numerous aspects of the key or parameters that have been supplied. Some of those checks use the supplied modulus value even if it has already been found to be too large. An application that calls DH_check() and supplies a key or parameters obtained from an untrusted source could be vulernable to a Denial of Service attack. The function DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check(). Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the '-check' option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

The marked package before 0.3.4 for Node.js allows attackers to cause a denial of service (CPU consumption) via unspecified vectors that trigger a "catastrophic backtracking issue for the em inline rule," aka a "regular expression denial of service (ReDoS)."
CVE-2015-8315 1 Vercel 1 Ms 2025-04-20 7.8 HIGH 7.5 HIGH
The ms package before 0.7.1 for Node.js allows attackers to cause a denial of service (CPU consumption) via a long version string, aka a "regular expression denial of service (ReDoS)."

An attacker may cause Denial of Service on a GitLab instance by exploiting a regex issue in how the application parses user agents.
CVE-2022-3514 1 Gitlab 1 Gitlab 2025-04-08 N/A 4.3 MEDIUM
An issue has been discovered in GitLab CE/EE affecting all versions starting from 6.6 before 15.5.7, all versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. An attacker may cause Denial of Service on a GitLab instance by exploiting a regex issue in the submodule URL parser.
CVE-2024-8998 1 Lunary 1 Lunary 2025-04-04 N/A 7.5 HIGH
A Regular Expression Denial of Service (ReDoS) vulnerability exists in lunary-ai/lunary version git f07a845. The server uses the regex /{.*?}/ to match user-controlled strings. In the default JavaScript regex engine, this regex can take polynomial time to match certain crafted user inputs. As a result, an attacker can cause the server to hang for an arbitrary amount of time by submitting a specially crafted payload. This issue is fixed in version 1.4.26.
CVE-2023-24038 2 Debian, Html-stripscripts Project 2 Debian Linux, Html-stripscripts 2025-04-02 N/A 7.5 HIGH
The HTML-StripScripts module through 1.06 for Perl allows _hss_attval_style ReDoS because of catastrophic backtracking for HTML content with certain style attributes.
CVE-2022-25927 1 Ua-parser-js Project 1 Ua-parser-js 2025-04-01 N/A 5.3 MEDIUM
Versions of the package ua-parser-js from 0.7.30 and before 0.7.33, from 0.8.1 and before 1.0.33 are vulnerable to Regular Expression Denial of Service (ReDoS) via the trim() function.
CVE-2025-2833 1 Zhyd 1 Oneblog 2025-04-01 5.0 MEDIUM 5.3 MEDIUM
A vulnerability was found in zhangyd-c OneBlog up to 2.3.9. It has been classified as problematic. Affected is an unknown function of the component HTTP Header Handler. The manipulation of the argument X-Forwarded-For leads to inefficient regular expression complexity. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
CVE-2022-25881 1 Http-cache-semantics Project 1 Http-cache-semantics 2025-03-27 N/A 5.3 MEDIUM
This affects versions of the package http-cache-semantics before 4.1.1. The issue can be exploited via malicious request header values sent to a server, when that server reads the cache policy from the request using this library.
CVE-2023-22792 1 Rubyonrails 1 Rails 2025-03-24 N/A 7.5 HIGH
A regular expression based DoS vulnerability in Action Dispatch <6.0.6.1,< 6.1.7.1, and <7.0.4.1. Specially crafted cookies, in combination with a specially crafted X_FORWARDED_HOST header can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately.
CVE-2024-49761 2 Netapp, Ruby-lang 3 Ontap Tools, Rexml, Ruby 2025-03-21 N/A 7.5 HIGH
REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or later include the patch to fix the vulnerability.
CVE-2024-41766 3 Ibm, Linux, Microsoft 3 Engineering Lifecycle Optimization Publishing, Linux Kernel, Windows 2025-03-21 N/A 7.5 HIGH
IBM Engineering Lifecycle Optimization - Publishing 7.0.2 and 7.0.3 could allow a remote attacker to cause a denial of service using a complex regular expression.
CVE-2024-6232 1 Python 1 Python 2025-03-20 N/A 7.5 HIGH
There is a MEDIUM severity vulnerability affecting CPython. Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives.
CVE-2023-6736 1 Gitlab 1 Gitlab 2025-03-20 N/A 6.5 MEDIUM
An issue has been discovered in GitLab EE affecting all versions starting from 11.3 before 16.7.6, all versions starting from 16.8 before 16.8.3, all versions starting from 16.9 before 16.9.1.

CVE-2024-12720 2025-03-20 N/A 5.3 MEDIUM
A Regular Expression Denial of Service (ReDoS) vulnerability was identified in the huggingface/transformers library, specifically in the file tokenization_nougat_fast.py. The vulnerability occurs in the post_process_single() function, where a regular expression processes specially crafted input. The issue stems from the regex exhibiting exponential time complexity under certain conditions, leading to excessive backtracking. This can result in significantly high CPU usage and potential application downtime, effectively creating a Denial of Service (DoS) scenario. The affected version is v4.46.3 (latest).
CVE-2024-10550 2025-03-20 N/A 7.5 HIGH
A vulnerability in the `/3/ParseSetup` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint applies a user-specified regular expression to a user-controllable string. This can be exploited by an attacker to cause inefficient regular expression complexity, leading to the exhaustion of server resources and making the server unresponsive.
CVE-2025-26042 2025-03-19 N/A 6.0 MEDIUM
Uptime Kuma >== 1.23.0 has a ReDoS vulnerability, specifically when an administrator creates a notification through the web service. If a string is provided it triggers catastrophic backtracking in the regular expression, leading to a ReDoS attack.
CVE-2020-6817 1 Mozilla 1 Bleach 2025-03-19 N/A 7.5 HIGH
bleach.clean behavior parsing style attributes could result in a regular expression denial of service (ReDoS). Calls to bleach.clean with an allowed tag with an allowed style attribute are vulnerable to ReDoS. For example, bleach.clean(..., attributes={'a': ['style']}).
