CVE-2026-67185 (GCVE-0-2026-67185)

Vulnerability from nvd – Published: 2026-07-28 16:30 – Updated: 2026-07-28 19:34 X_Open Source

Title

TinyWeb 0.0.8 Path Traversal via URL Path Component

Summary

TinyWeb through 0.0.8 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by submitting ../ sequences in the URL path, which are concatenated directly to the configured web root in HttpBuilder::buildResponse() without normalization, dot-segment removal, or boundary checks. Attackers can craft a single request with ../ sequences that pass through the URL parser unchanged and reach the filesystem call via HttpFile::setFile(), exposing sensitive files such as credential stores and private keys when the server process runs as root.

CVE-2026-67184 (GCVE-0-2026-67184)

Vulnerability from nvd – Published: 2026-07-28 16:28 – Updated: 2026-07-28 17:38 X_Open Source

Title

TinyWeb 0.0.8 Null Pointer Dereference DoS via Malformed HTTP Request

Summary

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted.

CVE-2026-67183 (GCVE-0-2026-67183)

Vulnerability from nvd – Published: 2026-07-28 16:26 – Updated: 2026-07-28 17:22 X_Open Source

Title

TinyWeb 0.0.8 Memory Leak DoS via HTTP Request Handling

Summary

TinyWeb through 0.0.8 contains a memory leak vulnerability that allows unauthenticated attackers to exhaust available memory by sending ordinary well-formed HTTP requests. Each request causes HttpParser::execute() to allocate Url objects, HttpHeaders objects, and HttpHeader instances via raw new expressions that are never freed due to missing destructors and unreachable delete calls, causing worker resident memory to grow monotonically by approximately 20 to 28 kB per request until the worker process is killed.

Severity

CVE-2026-67185 (GCVE-0-2026-67185)

Vulnerability from cvelistv5 – Published: 2026-07-28 16:30 – Updated: 2026-07-28 19:34 X_Open Source

Title

TinyWeb 0.0.8 Path Traversal via URL Path Component

Summary

TinyWeb through 0.0.8 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by submitting ../ sequences in the URL path, which are concatenated directly to the configured web root in HttpBuilder::buildResponse() without normalization, dot-segment removal, or boundary checks. Attackers can craft a single request with ../ sequences that pass through the URL parser unchanged and reach the filesystem call via HttpFile::setFile(), exposing sensitive files such as credential stores and private keys when the server process runs as root.

CVE-2026-67184 (GCVE-0-2026-67184)

Vulnerability from cvelistv5 – Published: 2026-07-28 16:28 – Updated: 2026-07-28 17:38 X_Open Source

Title

TinyWeb 0.0.8 Null Pointer Dereference DoS via Malformed HTTP Request

Summary

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted.

CVE-2026-67183 (GCVE-0-2026-67183)

Vulnerability from cvelistv5 – Published: 2026-07-28 16:26 – Updated: 2026-07-28 17:22 X_Open Source

Title

TinyWeb 0.0.8 Memory Leak DoS via HTTP Request Handling

Summary

TinyWeb through 0.0.8 contains a memory leak vulnerability that allows unauthenticated attackers to exhaust available memory by sending ordinary well-formed HTTP requests. Each request causes HttpParser::execute() to allocate Url objects, HttpHeaders objects, and HttpHeader instances via raw new expressions that are never freed due to missing destructors and unreachable delete calls, causing worker resident memory to grow monotonically by approximately 20 to 28 kB per request until the worker process is killed.
