curl: Public-suffix cookie injection when libpsl is disabled
Summary: When libcurl is built without libpsl, Domain attribute validation accepts public suffixes like .co.uk, allowing a malicious host to plant cookies that are later sent to unrelated sibling domains using the same cookie jar. AI assistance was used to draft this report. Steps to Reproduce: 1...
curl: libcurl WebSocket handshake accepts any Sec-WebSocket-Accept
Summary: libcurl upgrades to WebSocket without validating Sec-WebSocket-Accept, allowing a spoofed 101 response to complete the handshake and inject frames; AI assistance was used to draft this report. Steps to Reproduce: 1. Clone and build curl from source: git clone --depth=1...
Node.js: TLS PSK/ALPN Callback Exceptions Bypass Error Handlers, Causing DoS and FD Leak
A flaw was discovered in Node.js TLS error handling that allowed remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback were in use. Synchronous exceptions thrown during these callbacks bypassed standard TLS error handling paths, causing either immediate...
Apache Arrow IPC cached prebuffer path triggers signed integer overflow UB in read-range coalescing
Description Apache Arrow C++ commit d89c14b5d5203bc403fb62060fdf1ef2c0a49339 contains a signed integer overflow undefined behavior in the IO range coalescing logic, specifically in arrow/cpp/src/arrow/io/interfaces.cc:475 arrow::io::internal::CoalesceReadRanges. The overflow is reachable from...

curl: Functional Regression in Digest Authentication: Failure to handle optional spaces and escaped quotes
Summary A recent migration of the Digest authentication parsing logic to the curlxstr strparse API introduced two functional parsing regressions in lib/vauth/digest.c. 1. Optional Whitespace OWS Handling The current implementation fails to skip optional whitespace after comma delimiters in...
curl: A logic error in detect_proxy caused truncation of environment variable names for long protocol schemes.
In lib/url.c, the detectproxy function uses a fixed-size buffer, proxyenv20, to construct proxy environment variable names e.g., httpproxy. However, the curl URL parser lib/urlapi.c allows protocol schemes up to 40 characters MAXSCHEMELEN. When a protocol scheme longer than 12 characters is used,...
Rocket.Chat: Unauthenticated SSRF in Voxtelesys integration ('checkUrlForSsrf' Bypass via DNS rebinding)
An SSRF vulnerability was discovered in Rocket.Chat version 7.13.2 that was caused by a DNS rebinding attack. The vulnerability allowed an attacker to bypass a security check and access internal hosts on the same network as the Rocket.Chat server. The vulnerability was present in the SMS...
curl: Unbounded memory consumption via compressed HTTP responses (gzip/brotli/zstd)
During a review of curl's handling of response decompression, it was noticed that no limit exists on the final uncompressed data volume from compressed HTTP replies. Instead of setting constraints, the current design allows indefinite expansion during processing. This absence of limits could lead...

curl: Heap buffer overflow in Curl_ipv4_resolve_r due to incorrect buffer alignment and size calculation on AmigaOS
Summary: A heap-based buffer overflow exists in the AmigaOS-specific DNS resolution function Curlipv4resolver located in lib/amigaos.c. The function uses gethostbynamer with a fixed-size heap buffer CURLHOSTENTSIZE and performs incorrect pointer arithmetic when calculating the data buffer offset...

curl: Certificate Pinning Bypass with wolfSSL backend over HTTP/3
Summary: A security feature bypass exists in libcurl when built with the wolfSSL backend and HTTP/3 support. The Certificate Pinning feature --pinnedpubkey is silently ignored if the user also disables peer verification -k or --insecure . This behavior is inconsistent with other backends like...
Basecamp: Unauthenticated access to private files on app.fizzy.do via Active Storage URLs leads to information disclosure
A vulnerability was discovered where unauthenticated users could access private files and file previews on the application through Active Storage URLs. This vulnerability allowed information disclosure, as the files and previews could be accessed without any authentication or authorization checks...

curl: Curl Alt-Svc Parser Stack Buffer Overflow
cURL Alt-Svc Parser Stack Buffer Overflow Vulnerability Analysis In Simple Terms A critical security flaw was discovered in cURL versions 7.64.0-7.89.0 that allows attackers to run malicious code on your system by exploiting how cURL processes certain HTTP responses. When cURL receives a speciall...
Node.js: Node.js permission model bypass via unchecked Unix Domain Socket connections (UDS)
A flaw was discovered in Node.js's permission model that allowed Unix Domain Socket UDS connections to bypass network restrictions when --permission was enabled. Even without --allow-net, attacker-controlled inputs could connect to arbitrary local sockets via net, tls, or undici/fetch, breaking t...
