CVE-2026-35213

CVE-2026-35213 affects the @hapi/content package: three regexes used to parse Content-Type and Content-Disposition headers enable Regular Expression Denial of Service (ReDoS) via crafted header values. All versions up to 6.0.0 are vulnerable; remediation is to upgrade to 6.0.1 where the issue is ...

CVE-2026-35213 Regular Expression Denial of Service (ReDoS) in @hapi/content HTTP header parsing

@hapi/content provided HTTP Content- headers parsing. All versions of @hapi/content through 6.0.0 are vulnerable to Regular Expression Denial of Service ReDoS via crafted HTTP header values. Three regular expressions used to parse Content-Type and Content-Disposition headers contain patterns...

CVE-2026-34211 SandboxJS: Stack overflow DoS via deeply nested expressions in recursive descent parser

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, the @nyariv/sandboxjs parser contains unbounded recursion in the restOfExp function and the lispify/lispifyExpr call chain. An attacker can crash any Node.js process that parses untrusted input by supplying deeply nested expressions...

BIT-KYVERNO-2026-4789 CVE-2026-4789

PT-2026-30481

PilusCart 1.4.1 contains a SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the 'send' parameter. Attackers can submit POST requests to the comment submission endpoint with RLIKE-based boolean SQL injection payloads to...

Regular Expression Denial of Service (ReDoS)

Overview @hapi/content is a HTTP Content- headers parsing Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS through the Content-Type and Content-Disposition header parsing. An attacker can cause the application to become unresponsive by sending a singl...

@hapi/content: Regular Expression Denial of Service (ReDoS) in HTTP header parsing

All versions of @hapi/content through 6.0.0 are vulnerable to Regular Expression Denial of Service ReDoS via crafted HTTP header values. Three regular expressions used to parse Content-Type and Content-Disposition headers contain patterns susceptible to catastrophic backtracking. This has been...

CVE-2026-34939

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.searchtools 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...

Rack::Sendfile header-based X-Accel-Mapping regex injection enables unauthorized X-Accel-Redirect

Summary Rack::Sendfilemapaccelpath interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not escaped, an attacker who can supply X-Accel-Mapping to the backend can inject regex...

Rack has a root directory disclosure via unescaped regex interpolation in Rack::Directory

Summary Rack::Directory interpolates the configured root path directly into a regular expression when deriving the displayed directory path. If root contains regex metacharacters such as +, , or ., the prefix stripping can fail and the generated directory listing may expose the full filesystem pa...

Rack's greedy multipart boundary parsing can cause parser differentials and WAF bypass.

Summary Rack::Multipart::Parser extracts the boundary parameter from multipart/form-data using a greedy regular expression. When a Content-Type header contains multiple boundary parameters, Rack selects the last one rather than the first. In deployments where an upstream proxy, WAF, or intermedia...
