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...
Nextcloud: Authentication Bypass in ID4me handling via Missing JWT Signature Verification in User OIDC
An authentication bypass vulnerability was discovered in the ID4me handling in the OIDC implementation. The vulnerability was caused by missing JWT signature verification for user authentication...
Improper Access Control via Weak JWT Token Leads to Admin Takeover and Privilege Escalation
Description The application's session management is vulnerable to Authorization Bypass and Vertical Privilege Escalation. During dynamic analysis of the application's authentication flow, I discovered that the JSON Web Tokens JWT are signed with a weak secret key. This allowed me to perform an...
Arbitrary Code Execution via Unsafe torch.load() in Trainer Checkpoint Loading
Summary A critical arbitrary code execution vulnerability exists in HuggingFace Transformers' Trainer class. The loadrngstate method at src/transformers/trainer.py:3059 calls torch.load without the weightsonly=True parameter. While a safeglobals context manager wraps this call, it provides no...
TFSMLayer bypasses `safe_mode=True`, allowing attacker-controlled code execution during model inference
Summary TFSMLayer allows loading attacker-controlled TensorFlow SavedModels when deserializing a .keras model, even when safemode=True the default. While TensorFlow does not execute SavedModel functions during load, the attacker-controlled graph is registered during deserialization and executes...
curl: MQTT: Missing upper bound on incoming Remaining Length allows server-controlled long wait
Curl's MQTT implementation accepts any valid Remaining Length advertised by the server without an explicit upper bound beyond the MQTT spec maximum of 268,435,455 bytes. A malicious server can send a PUBLISH packet claiming this maximum size but provide only minimal payload, causing curl to wait...
curl: State Isolation Failure in Multiplexed Connections (Shared Auth Context)
Vulnerability: State Isolation Failure in Multiplexed Connections Shared Auth Context Product: libcurl Affected Versions: v7.43.0 - Current v8.x - All versions supporting HTTP/2 Multiplexing Severity: CRITICAL CVSS: 9.1 1. Executive Summary A fundamental design flaw exists in libcurl's state...
Nextcloud: SVG filter primitives bypass remote image blocking, enabling email tracking without consent.
A vulnerability was discovered in the HTML sanitizer of the Roundcube webmail application. The sanitizer did not properly handle the SVG filter primitive, allowing external resources to be loaded even when the "Block remote images" setting was enabled. This vulnerability could be used to track...
curl: Path Traversal in curl file:// Protocol Handler Allows Unauthorized File Access
Summary During my manual review of the file path handling logic in curl's source code, I noticed the absence of proper validation for directory traversal sequences, which I then verified through practical testing. I discovered that curl allows unauthorized access to arbitrary files through the...
curl: Alt-Svc bypasses credential leak protection (CVE-2018-1000007)
Summary I found a bug where curl's Alt-Svc implementation fails to strip sensitive authentication headers Authorization and Cookies when remapping a connection to a different host or port. This essentially bypasses the security fix for CVE-2018-1000007. While auditing the code, I noticed that...
8x8: jitsi-call-analytics: Unauthenticated arbitrary file write via path traversal in `/api/v1/uploads/analyze`
A path traversal vulnerability was discovered in the /api/v1/uploads/analyze endpoint of the jitsi-call-analytics backend. The vulnerability allowed unauthenticated users to write files within the configured RTCSTATSDOWNLOADSPATH directory. The issue was caused by the upload handler using...
curl: CRLF Injection in Gopher Protocol (`lib/gopher.c`)
Control characters slip through during URL handling in curl’s Gopher setup. Though null bytes get blocked by the REJECTZERO setting, returns and line feeds remain permitted. A specially built address using percent-encoded breaks - like %0D%0A - opens room for command insertion. Because of how...
curl: HTTP Request Smuggling and SSRF via CRLF Injection in Curl_add_custom_headers
Summary: A lack of CRLF validation in Curladdcustomheaders at lib/http.c:1761 allows users to inject arbitrary HTTP headers. This violation of RFC 7230 §3.2.4 leads to HTTP Request Smuggling and potential SSRF bypass. AI Disclosure: I utilized an AI assistant to aid in the initial code analysis a...
curl: MQTT Protocol Violation & Integer Overflow in libcurl
Executive Summary Vulnerability Type: CWE-190 Component: lib/mqtt.c Function: mqttdecodelen Affected Architectures: - All architectures: Protocol non-compliance leading to stream desynchronization - 32-bit architectures: Deterministic integer overflow in length decoding libcurl does not correctly...
curl: PROTOCOL-LEVEL: Persistent UDP Amplification and Cache Poisoning via Alt-Svc Logic Flaw
Summary A structural logic flaw in the libcurl Alt-Svc header parser allows attack attributes specifically persist and max-age to "leak" from one service definition to another. We have successfully chained this logic bug with curl's HTTP/3 QUIC support to demonstrate a Persistent UDP Amplificatio...
Nextcloud: Valid share tokens allow to access tempory upload files of share owner
A vulnerability was discovered that allowed access to temporary upload files of a share owner using valid share tokens...
