Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError. When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams.

CVE-2026-103831: Insecure deserialization vulnerability in the Psr16CacheAdapter component of the TrueLayer Magento 2 Plugin, due to the use of PHP's native unserialize() function without restrictions on the classes allowed when retrieving data stored in the cache. An attacker who already has the ability to write manipulated data to the cache backend used by Magento—such as Redis or Memcached—could inject specially crafted PHP objects and trigger their deserialization, potentially leading to arbitrary code execution via gadget strings available in the application environment. Exploitation therefore requires a prerequisite condition that allows writing to the cache infrastructure, either through access to the local file system or to a cache infrastructure accessible from the Magento environment.

MobilityDB version 1.3.0 and earlier contains an out-of-bounds read vulnerability in the MEOS binary and library WKB deserialization logic that allows unprivileged database users to crash the PostgreSQL backend process by supplying a crafted WKB payload with a negative length field. The negative length value wraps to a large unsigned size_t due to missing signed validation, bypasses an overflow-unsafe pointer arithmetic bounds check in wkb_parse_state_check(), and causes memcpy() in text_from_wkb_state() to operate with a corrupted unbounded length, resulting in a remote denial-of-service condition affecting all sessions on the PostgreSQL instance.

Sep 28, 2026ConvertPlus: Deserialization of Untrusted DataCVE-2026-87741 · WordPress plugins & themes · reported by WordfenceHigh 8.8
The ConvertPlus plugin for WordPress is vulnerable to Deserialization of Untrusted Data in all versions up to, and including, 3.6.3 via the style parameter of the cp_display_preview_modal AJAX action. The vulnerability exists because the action's nonce guard is gated behind an isset() check and fails open when the cp_admin_page_nonce parameter is omitted entirely, no capability check is performed on the callback, and sanitize_text_field() — applied to the $style value before it is concatenated directly into a shortcode string evaluated by do_shortcode() — does not strip shortcode delimiters, allowing an attacker to inject a second, fully attacker-controlled [smile_modal] invocation that causes smile_modal_popup() to pass attacker-supplied base64-decoded bytes to maybe_unserialize() with no allowed_classes restriction. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed o

Deserialization of Untrusted Data in Apache Roller 6.1.5 allows an unauthenticated remote attacker to cause deserialization of attacker-controlled bytes, because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication. The servlet is mapped unconditionally, so parsing occurs even when the global XML-RPC feature is set to disabled; no non-default configuration is required for this path. This can lead to remote code execution. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which disables the extension types and rejects requests when the XML-RPC feature is disabled.

MONAI before 1.5.2 contains a deserialization of untrusted data vulnerability in the algo_from_pickle function in monai/auto3dseg/utils.py. The function reads a .pkl file and passes its contents to pickle.loads without validating the data source or content.

MONAI versions before 1.6.0 contain a remote code execution vulnerability in the algo_from_pickle() function due to unsafe pickle.loads() deserialization in monai/auto3dseg/utils.py. Attackers can craft malicious pickle files that execute arbitrary system commands when deserialized by the vulnerable function.

pgPointcloud through 1.2.5 contains a heap out-of-bounds read vulnerability in dimensional patch WKB deserialization that allows authenticated database users to read adjacent heap memory. Attackers can supply crafted pcpatch values with attacker-controlled size fields to copy heap memory into stored patches for exfiltration or crash the PostgreSQL backend.

Sep 25, 2026In the Linux kernel, the following vulnerability has been resolved: ipvs: fix reversed sequence option serialization hton_seq() expects the host-order source CVE-2026-98078 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Medium 4.4
In the Linux kernel, the following vulnerability has been resolved: ipvs: fix reversed sequence option serialization hton_seq() expects the host-order source first and the unaligned network-order destination second. The version 1 sync sender passes these arguments in reverse for both sequence blocks. This leaves 24 bytes of the kmalloc-backed message unwritten. It may disclose stale heap data and replace the live connection sequence state with values read from the buffer. Pass the connection sequence state as the source and the message payload as the destination for both blocks.

Sep 24, 2026Deserialization of untrusted data in the command monitoring support of the MongoDB PHP Driver can cause class names embedded in document content to be honored wCVE-2026-96745 · Other software · MongoDB · reported by cna@mongodb.comMedium 6.3
Deserialization of untrusted data in the command monitoring support of the MongoDB PHP Driver can cause class names embedded in document content to be honored when the driver builds monitoring event objects. When an application registers a command monitoring subscriber and includes untrusted data in a database operation, an unauthenticated party who controls that data may cause an application class implementing the driver's persistable interface to be instantiated and its unserialization method invoked with the supplied data. The resulting impact depends on the classes available in the application.

Sep 24, 2026nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code.CVE-2026-88357 · Other software · reported by MITREHigh 7.5
nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
