| 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-2026-34939 | 2 Mervinpraison, Praison | 2 Praisonai, Praisonai | 2026-04-10 | 6.5 Medium |
| PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.search_tools() compiles a caller-supplied string directly as a Python regular expression with no validation, sanitization, or timeout. A crafted regex causes catastrophic backtracking in the re engine, blocking the Python thread for hundreds of seconds and causing a complete service outage. This issue has been patched in version 4.5.90. | ||||
| CVE-2026-31934 | 1 Oisf | 1 Suricata | 2026-04-08 | 7.5 High |

| CVE-2024-6434 | 1 Leap13 | 1 Premium Addons For Elementor | 2026-04-08 | 3.1 Low |
| The Premium Addons for Elementor plugin for WordPress is vulnerable to Regular Expression Denial of Service (ReDoS) in all versions up to, and including, 4.10.35. This is due to processing user-supplied input as a regular expression. This makes it possible for authenticated attackers, with Author-level access and above, to create and query a malicious post title, resulting in slowing server resources. | ||||
| CVE-2026-33671 | 2 Jonschlinkert, Micromatch | 2 Picomatch, Picomatch | 2026-04-02 | 7.5 High |
| Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are 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 can exhibit catastrophic backtracking on non-matching input. Applications are impacted when they allow untrusted users to supply glob patterns that are passed to `picomatch` for compilation or matching. In those cases, an attacker can cause excessive CPU consumption and block the Node.js event loop, resulting in a denial of service. Applications that only use trusted, developer-controlled glob patterns are much less likely to be exposed in a security-relevant way. This issue is fixed in picomatch 4.0.4, 3.0.2 and 2.3.2. Users should upgrade to one of these versions or later, depending on their supported release line. If upgrading is not immediately possible, avoid passing untrusted glob patterns to `picomatch`. Possible mitigations include disabling extglob support for untrusted patterns by using `noextglob: true`, rejecting or sanitizing patterns containing nested extglobs or extglob quantifiers such as `+()` and `*()`, enforcing strict allowlists for accepted pattern syntax, running matching in an isolated worker or separate process with time and resource limits, and applying application-level request throttling and input validation for any endpoint that accepts glob patterns. | ||||
| CVE-2025-70030 | 2 Sunbird, Sunbird-ed | 2 Sunbirded-portal, Sunbirded-portal | 2026-04-01 | 7.5 High |
| An issue pertaining to CWE-1333: Inefficient Regular Expression Complexity (4.19) was discovered in Sunbird-Ed SunbirdEd-portal v1.13.4. | ||||
| CVE-2026-33169 | 2 Rails, Rubyonrails | 2 Activesupport, Rails | 2026-03-25 | 5.3 Medium |
| Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. `NumberToDelimitedConverter` uses a lookahead-based regular expression with `gsub!` to insert thousands delimiters. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, the interaction between the repeated lookahead group and `gsub!` can produce quadratic time complexity on long digit strings. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch. | ||||
| CVE-2026-22178 | 1 Openclaw | 1 Openclaw | 2026-03-24 | 6.5 Medium |
| OpenClaw versions prior to 2026.2.19 construct RegExp objects directly from unescaped Feishu mention metadata in the stripBotMention function, allowing regex injection and denial of service. Attackers can craft nested-quantifier patterns or metacharacters in mention metadata to trigger catastrophic backtracking, block message processing, or remove unintended content before model processing. | ||||
| CVE-2024-39317 | 1 Torchbox | 1 Wagtail | 2026-03-20 | 6.5 Medium |
| Wagtail is an open source content management system built on Django. A bug in Wagtail's `parse_query_string` would result in it taking a long time to process suitably crafted inputs. When used to parse sufficiently long strings of characters without a space, `parse_query_string` would take an unexpectedly large amount of time to process, resulting in a denial of service. In an initial Wagtail installation, the vulnerability can be exploited by any Wagtail admin user. It cannot be exploited by end users. If your Wagtail site has a custom search implementation which uses `parse_query_string`, it may be exploitable by other users (e.g. unauthenticated users). Patched versions have been released as Wagtail 5.2.6, 6.0.6 and 6.1.3. | ||||
| CVE-2025-68475 | 2 Fedify, Fedify Project | 2 Fedify, Fedify | 2026-03-17 | 7.5 High |
| Fedify is a TypeScript library for building federated server apps powered by ActivityPub. Prior to versions 1.6.13, 1.7.14, 1.8.15, and 1.9.2, a Regular Expression Denial of Service (ReDoS) vulnerability exists in Fedify's document loader. The HTML parsing regex at packages/fedify/src/runtime/docloader.ts:259 contains nested quantifiers that cause catastrophic backtracking when processing maliciously crafted HTML responses. This issue has been patched in versions 1.6.13, 1.7.14, 1.8.15, and 1.9.2. | ||||
| CVE-2023-34104 | 2 Naturalintelligence, Redhat | 2 Fast-xml-parser, Migration Toolkit Applications | 2026-03-09 | 7.5 High |
| fast-xml-parser is an open source, pure javascript xml parser. fast-xml-parser allows special characters in entity names, which are not escaped or sanitized. Since the entity name is used for creating a regex for searching and replacing entities in the XML body, an attacker can abuse it for denial of service (DoS) attacks. By crafting an entity name that results in an intentionally bad performing regex and utilizing it in the entity replacement step of the parser, this can cause the parser to stall for an indefinite amount of time. This problem has been resolved in v4.2.4. Users are advised to upgrade. Users unable to upgrade should avoid using DOCTYPE parsing by setting the `processEntities: false` option. | ||||
| CVE-2024-41818 | 2 Naturalintelligence, Redhat | 4 Fast-xml-parser, Fast Xml Parser, Container Native Virtualization and 1 more | 2026-03-09 | 7.5 High |
| fast-xml-parser is an open source, pure javascript xml parser. a ReDOS exists on currency.js. This vulnerability is fixed in 4.4.1. | ||||
| CVE-2022-42965 | 1 Snowflake | 1 Snowflake Connector | 2026-03-06 | 3.7 Low |
| An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the snowflake-connector-python PyPI package, when an attacker is able to supply arbitrary input to the undocumented get_file_transfer_type method | ||||
| CVE-2024-58340 | 2 Langchain, Langchain-ai | 3 Langchain, Langchain Core, Langchain | 2026-03-05 | 7.5 High |
| LangChain versions up to and including 0.3.1 contain a regular expression denial-of-service (ReDoS) vulnerability in the MRKLOutputParser.parse() method (libs/langchain/langchain/agents/mrkl/output_parser.py). The parser applies a backtracking-prone regular expression when extracting tool actions from model output. An attacker who can supply or influence the parsed text (for example via prompt injection in downstream applications that pass LLM output directly into MRKLOutputParser.parse()) can trigger excessive CPU consumption by providing a crafted payload, causing significant parsing delays and a denial-of-service condition. | ||||
| CVE-2025-62484 | 1 Zoom | 4 Meeting Software Development Kit, Workplace, Workplace App and 1 more | 2026-02-26 | 8.1 High |
| Inefficient regular expression complexity in certain Zoom Workplace Clients before version 6.5.10 may allow an unauthenticated user to conduct an escalation of privilege via network access. | ||||
