Liberapay: Unauthenticated team "income/payments" export ignores donor privacy settings (hide_giving, hide_from_lists) and uses frozen visibility, exposing donat

A vulnerability was discovered in the unauthenticated team "income/payments" export feature of Liberapay. The vulnerability allowed an attacker to retrieve donor identity, exact donation amount, and donation dates for public donors, bypassing the donor's explicit privacy settings such as...

Node.js: Permission Model Bypass: `trace_events.createTracing().enable()` Writes Trace Logs Outside `--allow-fs-write`

A flaw in Node.js Permission Model enforcement was discovered that allowed traceevents.createTracing.enable to write trace logs outside of the --allow-fs-write setting. This vulnerability affected Node.js versions 22.x, 24.x, and 26.x...

curl: heap-use-after-free in curl_easy_cleanup() called from callback

Summary: Curlclose lib/url.c:214 calls curlmultiremovehandledata-multi, data and ignores the return value. When curleasycleanup is invoked from within a write/read/progress/header callback, multi-incallback is TRUE, so curlmultiremovehandle lib/multi.c:818-819 returns CURLMRECURSIVEAPICALL withou...

curl: libcurl upload read callbacks miss recursive API guard, allowing prohibited multi API reentry and ASAN-confirmed UAF

Summary: Several libcurl upload read callback paths invoke the application-provided CURLOPTREADFUNCTION without marking the easy handle as being inside a callback. As a result, recursive multi APIs that are correctly rejected from ordinary callbacks are accepted from these upload read callback...

curl: setopt(VERIFYPEER) from callback bypasses TLS verify on connection reuse

Summary: Curlsslconnconfigupdate overwrites conn-sslconfig.verifypeer when curleasysetoptCURLOPTSSLVERIFYPEER, ... is called, with no handshake-state guard — only ifdata-conn. Since setopt is documented as callable from callbacks setopt.c:2930, an application can connect with verifypeer=0 accepti...

curl: CURLSHOPT_UNSHARE race can cause UAF in shared SSL session cache during HTTPS transfer

Summary CURLSHOPTUNSHARE can free a shared SSL session cache while another thread is starting a normal HTTPS transfer with the same share handle. The failing transfer reaches the cache through curleasyperform, during the OpenSSL handshake. libcurl appears to try to reject this kind of lifetime...

Rocket.Chat: Authentication Bypass via XML Signature Wrapping in SAML SSO

The SAML SSO implementation in Rocket.Chat verified XML signatures but did not bind the validated signature to the samlp:Response or saml:Assertion. As a result, an attacker could submit a wrapped document carrying forged identity attributes alongside a valid signature made by the trusted IdP...

curl: ssh_config_matches is dead code: unauthorized SSH key reuse

Summary libcurl's SSH connection-reuse guard sshconfigmatches — added for CVE-2022-27782 and reaffirmed by CVE-2023-27538 — is dead code in every release since 7.83.1. It compares sshc-rsa / sshc-rsapub between a new transfer "needle" and a pooled connection, but on both sides those pointers are...

curl: mbedTLS / wolfSSL / rustls backends silently skip hostname verification when CURLOPT_SSL_VERIFYPEER=0

Summary When an application sets CURLOPTSSLVERIFYPEER=0 while keeping CURLOPTSSLVERIFYHOST=2 the default, the mbedTLS, wolfSSL, and rustls TLS backends silently skip the hostname-vs-certificate check. The OpenSSL, GnuTLS, and Schannel backends correctly preserve hostname checking under the same...

curl: UAF read in mev_pollset_diff() trace path after curl_easy_pause() in socket callback

Summary: The CVE-2026-9080 fix re-fetches the shentry after the socket callback inside mevshentryupdate, because curleasypause called from that callback re-enters mevassess and can free the entry. The same re-fetch was not applied at the caller, mevpollsetdiff, which dereferences its own entry...

curl: Use-after-free in `mev_forget_socket` when `curl_easy_pause()` is called from a `CURL_POLL_REMOVE` socket callback (incomplete fix of CVE-2026-9080)

Summary libcurl's event interface lets the application's socket callback CURLMOPTSOCKETFUNCTION call curleasypause. CVE-2026-9080 was issued for a use-after-free that this triggers, and the fix added a post-callback re-fetch of the socket-hash entry in the UPDATE leg mevshentryupdate,...

curl: CURLOPT_HAPROXY_CLIENT_IP lacks input validation, enabling HAProxy PROXY protocol injection

Summary The CURLOPTHAPROXYCLIENTIP option accepts an arbitrary string without validating that it is a valid IP address, and without stripping special characters such as \r\n CRLF or spaces. Because this value is embedded directly into the HAProxy PROXY protocol v1 header line, an attacker who can...

Node.js: Node --run POSIX positional argument escaping allows shell command injection

Summary Node.js node --run -- attempts to append positional arguments to a package script after escaping each argument for the shell. On POSIX platforms, the escaping logic handles single quotes incorrectly. A positional argument containing a single quote can break out of the intended quoted...

Node.js: HTTPS Agent PFX object-array key collision allows mTLS client identity reuse across different per-request certificates

A flaw in Node.js HTTPS Agent connection reuse was discovered that could cause PFX object-array key collisions, allowing mutual TLS mTLS client identities to be reused across requests configured with different client certificates. This vulnerability affected Node.js versions 26.x, 24.x, and 22.x...

Node.js: Permission Model bypass: process.report writes (and overwrites) files outside --allow-fs-write paths

A flaw was found in the Node.js Permission Model enforcement that allowed the process.report function to write and overwrite files outside the --allow-fs-write paths...

Nintendo: [Splatoon 3] Kick other players with NplnLogin message

A vulnerability was discovered that allowed players to kick other players from a Splatoon 3 game using an NplnLogin message...

Node.js: HTTPS Agent TLS session reuse skips hostname verification across identity policies (incomplete fix of CVE-2026-48934)

A vulnerability was identified in Node.js where HTTPS Agent TLS session reuse skipped hostname verification across identity policies, which was an incomplete fix for CVE-2026-48934. This affected Node.js versions 22.x, 24.x, and 26.x...

curl: Vulnerability Report: Buffer Overflow in Path Sanitization

Vulnerability Report: Buffer Overflow in Path Sanitization Summary Multiple buffer overflow vulnerabilities exist in the src/tooldoswin.c file due to insufficient bounds checking and improper memory management in path sanitization functions. Affected Components - sanitizefilename line 180 -...

curl: Secure cookies leaked to HTTP origins through HTTPS forwarding proxy

Summary: When curl accesses an http:// origin through an HTTPS forwarding proxy, it sends Secure cookies in the request. The cookies travel in cleartext between the proxy and the origin server, visible to the proxy operator and anyone on that network path. curl also reports CURLINFOSCHEME as...
