CVE-2026-33538: Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.58 and 9.6.0-alpha.52, an unauthenticated attacker can cause denial of service by sending authentication requests with arbitrary, unconfigured provider names. The server executes a database query for each unconfigured provider before rejecting the request, and since no database index exists for unconfigured providers, each request triggers a full collection scan on the user database. This can be parallelized to saturate database resources. This issue has been patched in versions 8.6.58 and 9.6.0-alpha.52.
CVE-2026-32854: LibVNCServer versions 0.9.15 and prior (fixed in commit dc78dee) contain null pointer dereference vulnerabilities
LibVNCServer versions 0.9.15 and prior (fixed in commit dc78dee) contain null pointer dereference vulnerabilities in the HTTP proxy handlers within httpProcessInput() in httpd.c that allow remote attackers to cause a denial of service by sending specially crafted HTTP requests. Attackers can exploit missing validation of strchr() return values in the CONNECT and GET proxy handling paths to trigger null pointer dereferences and crash the server when httpd and proxy features are enabled.
CVE-2026-4775: A flaw was found in the libtiff library.
A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.
CVE-2026-30662: ConcreteCMS v9.4.7 contains a Denial of Service (DoS) vulnerability in the File Manager component.
ConcreteCMS v9.4.7 contains a Denial of Service (DoS) vulnerability in the File Manager component. The 'download' method in 'concrete/controllers/backend/file.php' improperly manages memory when creating zip archives. It uses 'ZipArchive::addFromString' combined with 'file_get_contents', which loads the entire content of every selected file into PHP memory. An authenticated attacker can exploit this by requesting a bulk download of large files, triggering an Out-Of-Memory (OOM) condition that causes the PHP-FPM process to terminate (SIGSEGV) and the web server to return a 500 error.
CVE-2026-30653: An issue in Free5GC v.4.2.0 and before allows a remote attacker to cause a denial of service via the function Hand
An issue in Free5GC v.4.2.0 and before allows a remote attacker to cause a denial of service via the function HandleAuthenticationFailure of the component AMF
CVE-2026-33418: DiceBear is an avatar library for designers and developers.
DiceBear is an avatar library for designers and developers. Prior to version 9.4.2, the `ensureSize()` function in `@dicebear/converter` used a regex-based approach to rewrite SVG `width`/`height` attributes, capping them at 2048px to prevent denial of service. This size capping could be bypassed by crafting SVG input that causes the regex to match a non-functional occurrence of `<svg` before the actual SVG root element. When the SVG is subsequently rendered via `@resvg/resvg-js` on the Node.js code path, it renders at the attacker-specified dimensions, potentially causing out-of-memory crashes. In version 9.4.2, the regex-based approach has been replaced with XML-aware processing using `fas
CVE-2019-25645: WinAVI iPod/3GP/MP4/PSP Converter 4.4.2 contains a denial of service vulnerability that allows local attackers to
WinAVI iPod/3GP/MP4/PSP Converter 4.4.2 contains a denial of service vulnerability that allows local attackers to crash the application by processing malformed AVI files.

CVE-2019-25642: Bootstrapy CMS contains multiple SQL injection vulnerabilities that allow unauthenticated attackers to execute arb
Bootstrapy CMS contains multiple SQL injection vulnerabilities that allow unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through POST parameters. Attackers can inject SQL payloads into the thread_id parameter of forum-thread.php, the subject parameter of contact-submit.php, the post-id parameter of post-new-submit.php, and the thread-id parameter to extract sensitive database information or cause denial of service.
CVE-2019-25640: Inout Article Base CMS contains SQL injection vulnerabilities that allow unauthenticated attackers to manipulate d
Inout Article Base CMS contains SQL injection vulnerabilities that allow unauthenticated attackers to manipulate database queries through the 'p' and 'u' parameters.

CVE-2026-3260: Rejected reason: The Undertow web server enforces a default maximum HTTP request entity size limit.
Rejected reason: The Undertow web server enforces a default maximum HTTP request entity size limit. Any request (including GET or HEAD) containing a body that exceeds this configurable limit is safely dropped by the server, preventing single-request Resource Exhaustion (Out of Memory) Denial of Service attacks.
CVE-2026-33241: Salvo is a Rust web framework.
Salvo is a Rust web framework. Prior to version 0.89.3, Salvo's form data parsing implementations (`form_data()` method and `Extractible` macro) do not enforce payload size limits before reading request bodies into memory. This allows attackers to cause Out-of-Memory (OOM) conditions by sending extremely large payloads, leading to service crashes and denial of service. Version 0.89.3 contains a patch.
CVE-2026-33176: Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework.
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. `1e10000`), which `BigDecimal` expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVE-2026-33174: Active Storage allows users to attach cloud and local files in Rails applications.
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when serving files through Active Storage's proxy delivery mode, the proxy controller loads the entire requested byte range into memory before sending it. A request with a large or unbounded Range header (e.g. `bytes=0-`) could cause the server to allocate memory proportional to the file size, possibly resulting in a DoS vulnerability through memory exhaustion. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVE-2026-26209: cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) serialization format.
cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) serialization format. Versions prior to 5.9.0 are vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding deeply nested CBOR structures. This vulnerability affects both the pure Python implementation and the C extension `_cbor2`. The C extension relies on Python's internal recursion limits `Py_EnterRecursiveCall` rather than a data-driven depth limit, meaning it still raises `RecursionError` and crashes the worker process when the limit is hit. While the library handles moderate nesting levels, it lacks a hard depth limit. An attacker can supply a crafted CBOR payloa

Attackers can exploit unchecked arithmetic operations in sparse accessor validation to cause heap buffer over-reads in cgltf_calc_index_bound(), resulting in denial of service crashes and potential memory disclosure.
CVE-2026-33483: WWBN AVideo is an open source video platform.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `aVideoEncoderChunk.json.php` endpoint is a completely standalone PHP script with no authentication, no framework includes, and no resource limits. An unauthenticated remote attacker can send arbitrary POST data which is written to persistent temp files in `/tmp/` with no size cap, no rate limiting, and no cleanup mechanism. This allows trivial disk space exhaustion leading to denial of service of the entire server. Commit 33d1bae6c731ef1682fcdc47b428313be073a5d1 contains a patch.
