curl: Duplicate chunked Transfer-Encoding lets a malicious origin smuggle a response across reused HTTP proxy connections

TL;DR A malicious HTTP origin can send Transfer-Encoding: chunked, chunked, gzip through a reusable HTTP proxy connection to bypass curl's "chunked must be last" guard, queue a forged HTTP response after its own response, and make curl parse that queued data as the response for a later request to...

Essity: Unauthenticated reflected XSS in Essity "Network Toolbox" CGI (████████ ████████

Summary Legacy Perl "Network Toolbox" CGI at ████████ reflects packetsize into the HTML response without output encoding. When packetsize is non-integer, the script echoes the raw value inside an error element, allowing arbitrary HTML/JS injection. No auth required; no CSP on the response. Steps ...

curl: Incomplete Suppression of Transfer-Encoding: chunked Header in HTTP/2 After Redirect From HTTP/1.1

When curl send a request with Transfer-Encoding: chunked using HTTP/1.1, and follows a redirect to an HTTP/2 endpoint, the uploadchunky flag is not properly reset. As a result, the Transfer-Encoding: chunked header is sent in the subsequent request even when HTTP/2 is negotiated/used. This violat...

curl: CVE-2026-11856: cross-origin Digest auth state leak

Summary: This issue is the HTTP sibling to the previously disclosed RTSP Digest auth leak. When an application uses libcurl and reuses the same easy handle for sequential transfers the documented best practice, the Digest authentication state captured from the first origin is silently sent to the...

Revive Adserver: Reflected XSS in stats‑video.php via improperly encoded URL parameters

A reflected XSS vulnerability was discovered in the stats‑video.php script due to improper encoding of user input in the URL parameters...

curl: Trailing-Dot Hostname in Redirect Silently Strips Client Certificate and Auth Credentials

Summary When curl follows a redirect where the Location header contains a hostname with a trailing dot e.g., https://example.com./path, Curlpeerequal in peer.c:321-330 compares the original hostname example.com against the redirect target example.com. using curlstrequal, which does not normalize...

curl: curl-ipv4-percent-normalization-SSRF

Summary: six or fewer sentences describing the issue in your own human voice and optionally a short proof-of-concept script Affected version Which curl/libcurl version are you using to reproduce? On which platform? curl -V typically generates good output to include Steps To Reproduce: add details...

8x8: jitsi-meet: Prosody/Jigasi missing header whitelist in mod_filter_iq_rayo allows arbitrary SIP header injection and Caller ID spoofing

A vulnerability was discovered in the Prosody and Jigasi components of Jitsi Meet. The Prosody filter implemented an incomplete blocklist that allowed authenticated users with outbound-call privileges to inject arbitrary SIP headers, enabling Caller ID spoofing on outgoing SIP calls in environmen...

curl: CVE-2026-11564: Native CA trust persist

A vulnerability was discovered in the libcurl library where a native CA trust could persist after an easy handle switches to custom CA material. The vulnerability was found to affect builds of libcurl that enable the native CA trust feature. The issue stemmed from the fact that the library did no...

curl: CVE-2026-11586: WS Auto-PONG memory exhaustion

Summary: TL;DR: a remote WebSocket peer can make default curl/libcurl grow memory until timeout or OOM by sending legal PING frames while refusing to read the client's automatic PONGs. curl automatically replies to each received WebSocket PING with a PONG unless CURLWSNOAUTOPONG is set. In...

curl: SSH/SFTP connection reuse can bypass SSH key identity after ssh_config_matches removal

Summary: libcurl's SSH/SFTP connection reuse logic no longer binds a pooled SSH connection to the SSH key identity requested by the new transfer. After sshconfigmatches was removed, urlmatchprotoconfig again has no SSH-specific check for CURLOPTSSHPUBLICKEYFILE or CURLOPTSSHPRIVATEKEYFILE. An...

MariaDB: Stack Buffer Overflow in mariadb-dump quote_name() Allows Malicious Server to Execute Arbitrary Code on Client

A stack buffer overflow was discovered in the quotename function of the mariadb-dump client application. The overflow occurred due to a lack of length validation on table names returned by a malicious MySQL server. This allowed a server to provide an excessively long table name that would overflo...

curl: SOCKS5 no-auth accepted despite username/password-only authentication

Summary: curl/libcurl appears to allow unauthenticated SOCKS5 negotiation even when the caller explicitly configures username/password-only SOCKS5 authentication. With --socks5-basic and SOCKS5 credentials set, curl still advertises both SOCKS5 method 0x00 no authentication and 0x02...

curl: libcurl: HTTP/1.x bare LF byte in response header value enables cookie jar pollution and POST body/credential exfiltration via redirect — RC=0, curl 8

Summary curl's HTTP/1.x response header parser splits header lines using a single memchrbuf, '\n', blen call lib/http.c:4457, with no awareness of whether the current position is inside a quoted-string value. A server response containing any header field whose value embeds a raw LF byte \x0a caus...

curl: GnuTLS OCSP stapling accepts unrelated SingleResponse (no cert-ID binding)

Summary This report describes a variant of the publicly disclosed curl vulnerability CVE-2020-8286 OCSP stapling verification bypass, found in the GnuTLS TLS backend lib/vtls/gtls.c. The original CVE affected the NSS backend; this variant reproduces the same logical class of defect — accepting...

curl: CVE-2026-11352: QUIC zero-length UDP datagrams busy-loop

Summary: curl's QUIC UDP receive helper ignores zero-length UDP datagrams before counting them against the per-call packet budget. On Linux, recvmmsgpackets loops while pkts maxpkts, but if!mmsgi.msglen continue; runs before pkts is incremented. The recvmsgpackets backend has the same no-progress...

Mozilla: Unauthenticated RCE in Taskcluster web-server via GraphQL filter argument (sift $where)

A vulnerability was discovered in the Taskcluster web-server that allowed unauthenticated remote code execution through the GraphQL filter argument. The issue was caused by the use of the 'sift' library, which compiled the filter's '$where' string into a function using 'new Function' and executed...

MariaDB: Stack Buffer-Overflow in MariaDB Charset_collation_map_st::insert_or_replace()

A stack-based buffer overflow was discovered in the MariaDB Server's Charsetcollationmapst::insertorreplace function. The function copied user-supplied charset and collation identifiers into fixed-size stack buffers using strmake with the attacker-controlled token length as the size bound instead...
