curl: Digest Authentication Header Injection

Summary The Digest authentication implementation in libcurl fails to properly escape the uri parameter in the Authorization header. While other parameters like username, realm, and nonce are correctly escaped using authdigeststringquoted, the uri is inserted raw into the header. This allows an...

curl: Gopher Protocol Command Injection (SSRF Smuggling)

Summary The curl Gopher protocol handler is vulnerable to command injection through URL-encoded CRLF sequences in the path. This allows an attacker to "smuggle" additional Gopher selectors or arbitrary commands into a single Gopher request. By using %0d%0a in the URL, an attacker can break the...

curl: Use-After-Free in curl_easy_nextheader when reusing header handle across requests

. The API returns struct curlheader objects that internally reference libcurl-owned linked list nodes. When a new request is performed on the same CURL handle, libcurl frees and rebuilds the internal header list, but previously returned struct curlheader objects remain valid to the application an...

Nextcloud: Shared smart albums in the Photos app can expose files outside the album owner's configured source folders

A vulnerability was discovered in a file manager component of a file sharing application. The vulnerability allowed an attacker to access files outside of the intended shared folder by configuring more permissive search paths than the victim intended. This resulted in unauthorized information...

GitHub: Missing Access Control in MigrationFile allows attacker to upload files to any Migration

A Missing Authorization vulnerability was identified in GitHub Enterprise Server that allowed unauthorized content to be uploaded to a user's repository migration export due to a missing authorization check in the repository migration upload endpoint. The vulnerability could be exploited by...

curl: Heap Out-of-Bounds Read in lib/http2.c via Malformed PUSH_PROMISE Headers

Summary A heap-based out-of-bounds read vulnerability exists in libcurl's HTTP/2 implementation. The onheader callback in lib/http2.c incorrectly treats header names and values provided by nghttp2 as null-terminated C-strings. Specifically, passing these pointers to curlmaprintf with the %s forma...

curl: CRLF Injection in HTTP header values allows arbitrary header injection

curl allows carriage return \r and line feed \n characters inside HTTP header values. When attacker-controlled data is used in a header value e.g., Authorization: Bearer , curl construct and sends a malformed HTTP request containing injected headers. This violates HTTP specification RFC 7320 /RFC...

Stored XSS in Home Feed via Post Content Lead to Account Takeover

Description A Stored Cross-Site Scripting XSS vulnerability was identified in the social feature of the application. The backend fails to sanitize user-provided content in the post creation endpoint. This allows an attacker to inject and store malicious JavaScript, which is then executed in the...

curl: inconsistently Rejection Logic in file:// URLs with Authority

curl's file:// protocol handler inconsistently applies path sanitization. in reject file://../ as Bad File:// URL" but allows the same traversal when an authority/host e.g.,localhost is present file://localhost/../. this inconsistency misleads developers who rely on the bad file:// URL error for...

curl: Stack Buffer Overflow in mprintf.c formatting function (fallback path)

Summary A stack-based buffer overflow exists in mprintf.c within the outdouble function. This vulnerability affects builds where HAVESNPRINTF is undefined, forcing the use of the legacy sprintf function. The logic responsible for calculating the maximum safe precision maxprec for floating-point...

Path Traversal in Agent Flows via `uuid` (Arbitrary .json File Read/Delete)

Description : Summary I discovered a Path Traversal vulnerability in the AgentFlows component that allows reading and deleting arbitrary .json files on the server. The issue stems from the improper usage of path.join combined with normalizePath. The application resolves the file path using user...
