8.6CVE-2026-52747debianmodsecurity+3
EPSS score
0.48%
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Prior to 3.0.16, the multipart/form-data request body parser in libmodsecurity silently removes embedded line breaks from non-file form-field values before exporting them to ARGS and ARGS_POST because src/request_body_processor/multipart.cc overwrites reserved bytes in m_reserve instead of appending the current buffer. This creates a parser differential between ModSecurity and backend applications that preserve line breaks in form fields, allowing rules that inspect ARGS or ARGS_POST to miss payloads whose dangerous syntax depends on a line break. This issue is fixed in version 3.0.16.

EPSS score
0.49%
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.0 to before 3.0.15, there is an unhandled exception (std::out_of_range) caused by unsigned integer underflow in libmodsecurity3 if the user (administrator) uses a rule any of @verifySSN, @verifyCPF, or @verifySVNR. This vulnerability is fixed in 3.0.15.

EPSS score
0.52%
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Libmodsecurity is one component of the ModSecurity v3 project. A segmentation fault occurs when a rule using the t:hexDecode transformation inspects a query string parameter containing a single character. An attacker can exploit this to crash worker processes, causing a denial of service. Service resumes once the attack stops as worker processes recover from the segfault. All versions before 3.0.15 of libModSecurity3 are affected. This has been patched in version 3.0.15.
6.5CVE-2026-3816owaspdefectdojo
EPSS score
0.74%
A security vulnerability has been detected in OWASP DefectDojo up to 2.55.4. This vulnerability affects the function input_zip.read of the file parser.py of the component SonarQubeParser/MSDefenderParser. The manipulation leads to denial of service. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 2.56.0 is able to resolve this issue. The identifier of the patch is e8f1e5131535b8fd80a7b1b3085d676295fdcd41. Upgrading the affected component is recommended.
7.5CVE-2026-33691corerulesetcoreruleset+4
EPSS score
1.58%
The OWASP core rule set (CRS) is a set of generic attack detection rules for use with compatible web application firewalls. Prior to versions 3.3.9 and 4.25.0, a bypass was identified in OWASP CRS that allows uploading files with dangerous extensions (.php, .phar, .jsp, .jspx) by inserting whitespace padding in the filename (e.g. photo. php or shell.jsp ). The affected rules do not normalize whitespace before evaluating the file extension regex, so the dot-extension check fails to match. This issue has been patched in versions 3.3.9 and 4.25.0.

An issue in OWASP DefectDojo before v.1.5.3.1 allows a remote attacker to escalate privileges via the user permissions component.
9.8CVE-2023-38199debianmodsecurity-crs+2
EPSS score
0.75%
coreruleset (aka OWASP ModSecurity Core Rule Set) through 3.3.4 does not detect multiple Content-Type request headers on some platforms. This might allow attackers to bypass a WAF with a crafted payload, aka "Content-Type confusion" between the WAF and the backend application. This occurs when the web application relies on only the last Content-Type header. Other platforms may reject the additional Content-Type header or merge conflicting headers, leading to detection as a malformed header.

Trustwave ModSecurity 3.x before 3.0.10 has Inefficient Algorithmic Complexity.
7.5CVE-2023-28882chainguardmodsecurity+4
EPSS score
0.73%
Trustwave ModSecurity 3.0.5 through 3.0.8 before 3.0.9 allows a denial of service (worker crash and unresponsiveness) because some inputs cause a segfault in the Transaction class for some configurations.
2.6CVE-2006-3841owaspwebscarab
EPSS score
1.37%
Cross-site scripting (XSS) vulnerability in WebScarab before 20060718-1904, when used with Microsoft Internet Explorer 6 SP2 or Konqueror 3.5.3, allows remote attackers to inject arbitrary web script or HTML via the URL, which is not sanitized before being returned in an error message when WebScarab is not able to access the URL.
