curl: Heap-buffer-overflow in `Curl_ssl_push_certinfo_len()` — sole bounds check is `DEBUGASSERT`
Summary Curlsslpushcertinfolen in lib/vtls/vtls.c uses DEBUGASSERTcertnum numofcerts as its only bounds check before writing a heap pointer into ci-certinfocertnum. DEBUGASSERT is a no-op in every release/production build lib/curlsetup.h:1084. Any mismatch between the count passed to...
curl: Stack exhaustion in MIME multipart reading with deeply nested subparts
Summary: The MIME read path uses mutually recursive helpers for nested multipart structures without enforcing a recursion depth limit. A sufficiently deep tree of nested curlmimesubparts objects causes stack exhaustion when libcurl starts reading the MIME body. The attached PoC builds a deeply...

curl: Use-after-free in `curl_easy_ssls_export()` during callback re-entrancy
Summary: curleasysslsexport iterates the SSL session list and invokes a caller-provided callback for each entry. If that callback calls curleasysslsimport on the same easy handle, the import path can evict and free the current session node while the export loop still holds it. The subsequent...
Tenable Identity Exposure < 3.77.17 Multiple Vulnerabilities (TNS-2026-11)
The version of the Tenable Identity Exposure running on the remote host is prior to 3.77.17.

curl: Digest Auth State Leak on Cross-Origin Redirect via Netrc - Username and Password Hash Sent to Wrong Host
Summary When curl follows an HTTP redirect from hostA to hostB using --netrc --digest -L, Digest authentication state nonce, realm from hostA persists and is combined with hostB's netrc credentials to generate an unsolicited Digest Authorization header sent to hostB. This leaks hostB's username i...
curl: CVE-2026-6429: netrc credential leak with reused proxy connection
Summary: libcurl can leak .netrc-derived host Authorization credentials across redirected hosts when an HTTP proxy connection is reused. In the PoC, .netrc contains credentials only for a.test, but after a.test redirects to b.test and then c.test over the same keep-alive proxy connection, libcurl...

curl: CVE-2026-6276: stale custom cookie host causes cookie leak
Summary: libcurl keeps a stale data-state.aptr.cookiehost after a request that uses a custom Host: header. On later requests on the same easy handle, when no custom Host: is used, libcurl still reuses that stale value for outgoing cookie selection lib/http.c:2560-2563 and incoming Set-Cookie...
