| CVE-2026-33231 | 1 Nltk | 1 Nltk | 2026-09-09 | 7.5 High |
| NLTK (Natural Language Toolkit) is a suite of open source Python modules, data sets, and tutorials supporting research and development in Natural Language Processing. In versions 3.9.3 and prior, `nltk.app.wordnet_app` allows unauthenticated remote shutdown of the local WordNet Browser HTTP server when it is started in its default mode. A simple `GET /SHUTDOWN%20THE%20SERVER` request causes the process to terminate immediately via `os._exit(0)`, resulting in a denial of service. Commit bbaae83db86a0f49e00f5b0db44a7254c268de9b patches the issue. | ||||
| CVE-2026-30922 | 1 Pyasn1 | 1 Pyasn1 | 2026-09-09 | 7.5 High |
| pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE` (`0x30`) or `SET` (`0x31`) tags with "Indefinite Length" (`0x80`) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all available memory (OOM), crashing the host application. This is a distinct vulnerability from CVE-2026-23490 (which addressed integer overflows in OID decoding). The fix for CVE-2026-23490 (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this specific issue. | ||||
| CVE-2026-2050 | 1 Gimp | 1 Gimp | 2026-09-09 | 7.8 High |
| GIMP HDR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of HDR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28266. | ||||
| CVE-2025-67030 | 1 Codehaus-plexus | 1 Plexus-utils | 2026-09-09 | 8.8 High |
| Directory Traversal vulnerability in the extractFile method of org.codehaus.plexus.util.Expand in plexus-utils before 6d780b3378829318ba5c2d29547e0012d5b29642. This allows an attacker to execute arbitrary code | ||||
| CVE-2026-74860 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-09-09 | 8.5 High |
| A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings. | ||||

| CVE-2026-4765 | 1 Rd Station Conversas | 1 Tallos Chat | 2026-09-09 | N/A |
| Self Cross-Site Scripting (Self-XSS) vulnerability in the RD Station Conversas chat feature. The vulnerability lies in the ‘name’ parameter of the initialisation process due to incorrect sanitisation of user-supplied input. Exploitation allows specially crafted JavaScript code to be injected, which is executed within the context of the user’s own session who provides the payload. The demonstrated impact is limited to the user who enters and executes the payload. | ||||

| CVE-2026-12611 | 1 Eclipse | 1 Jetty | 2026-09-09 | N/A |
| A client may issue HTTP/2 requests to a Jetty server that result in blocking writes that are never unblocked, eventually causing all threads to be blocked and the whole server to become unresponsive. This is caused by a race condition in the server when handling RST_STREAM frames and GOAWAY frames sent by the client. The race condition "resets" the HTTP2Flusher.terminated, previously set to a non-null value, to the null value, allowing entries to be enqueued in the flusher that however will never be processed. These unprocessed entries are the ones that would unblock the write-blocked threads. | ||||
