Heap out-of-bounds write in rsync 3.2.5 through 3.4.x allows remote unauthenticated attackers to corrupt heap memory by supplying a crafted files-from entry to any exposed rsync daemon module. Critically, the flaw is exploitable against read-only daemon modules - a configuration commonly treated as a safe exposure boundary - by providing a path containing both an interior and trailing backslash, causing add_implied_include() to under-size its destination buffer and write one attacker-controlled byte past the allocation end. No public exploit has been identified at time of analysis, though the CVSS 4.0 score of 8.8 reflects the unauthenticated network attack vector and high availability impact.
Remote code execution in PostgreSQL's portal/cursor subsystem allows any authenticated database user to execute arbitrary code as the OS-level process owner (typically 'postgres') by re-creating a named cursor with an incompatible result type. All actively supported major branches are affected - versions prior to 14.24, 15.19, 16.15, 17.11, and 18.5. No public exploit or active exploitation has been identified at time of analysis, but the low attack complexity and minimal authentication requirement (any valid login) make this a critical patch priority for the ubiquitous open-source RDBMS.
Remote code execution in PostgreSQL 18.x (all minor versions before 18.5) is achievable by any authenticated object creator through a type confusion flaw in pg_restore_attribute_stats(), which conflates range and multirange values to corrupt memory and gain code execution as the OS user running the database process. The CVSS 8.8 score reflects a low-privilege, low-complexity network exploit path with full confidentiality, integrity, and availability impact. No public exploit code or active exploitation has been identified at the time of analysis, but the RCE primitive combined with the low privilege bar makes this a high-priority patch target for all PostgreSQL 18 deployments.
Type confusion in PostgreSQL's 'internal' pseudo-type enforcement enables any authenticated database user to execute arbitrary code as the operating system user running the database process. The vulnerability arises because access controls blocking SQL-layer callers from invoking C-language functions that accept 'internal' arguments contained coverage gaps, allowing a crafted function call to corrupt memory and achieve OS-level code execution. Fixed versions are PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24; no public exploit or CISA KEV listing has been identified at time of analysis.
Type confusion in PostgreSQL's 'refint' contrib module enables any low-privileged database user with object creation rights to execute arbitrary code as the operating system user hosting the PostgreSQL service. Affected are all active PostgreSQL branches prior to versions 18.5, 17.11, 16.15, 15.19, and 14.24. Notably, the fix was silently committed to the PostgreSQL git repository under the subject 'refint: Remove plan cache.' without a CVE assignment, meaning vulnerable installations may have remained unpatched far longer than typical because administrators had no security signal to act on. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
PostgreSQL's ctid data type selectivity estimator mishandles non-ctid input through a type confusion flaw (CWE-843), enabling any low-privileged database user with object-creation rights to read approximately 4 bytes of arbitrary server memory per query. All supported major versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. No public exploit code or CISA KEV listing has been identified at time of analysis, but the vendor explicitly acknowledges that substantial memory value recovery is possible.
Out-of-bounds write in the MongoDB BI Connector ODBC Driver allows an authenticated low-privileged user to crash the client application performing data reads through the connector. The driver fails to validate destination buffer size when converting floating-point column values to their string representations, enabling memory corruption when sufficiently large float values are encountered. No public exploit code has been identified at time of analysis, and a vendor-confirmed fix is available in version 1.4.9.
Remote code execution in IBM i (formerly OS/400) versions 7.3, 7.4, 7.5, and 7.6 arises from a stack-based buffer overflow that lets a remote attacker run arbitrary code on the host operating system.

Remote code execution within Chrome's renderer sandbox is possible in Google Chrome versions prior to 151.0.7922.137 due to a use-after-free flaw in the HTML subsystem. An unauthenticated remote attacker can exploit this by inducing a victim to visit a crafted HTML page, triggering heap corruption that results in arbitrary code execution scoped to the sandboxed renderer process. No public exploit code has been identified at time of analysis, and EPSS stands at a low 0.31% (23rd percentile), suggesting limited attacker uptake despite the high CVSS score of 8.8.
Use-after-free in Google Chrome's Extensions subsystem prior to version 151.0.7922.137 enables an attacker to execute arbitrary code inside the Chrome sandbox by convincing a target to install a crafted malicious extension. The vulnerability class (CWE-416) indicates improper memory management in the extension handling code, where a freed memory reference is later dereferenced, corrupting heap state in a way an attacker can direct toward code execution. No public exploit or CISA KEV listing is identified at time of analysis; exploitation requires deliberate social engineering to achieve extension installation.
Sandbox escape in Google Chrome on macOS exploits a use-after-free condition in the TabStrip browser component, enabling a renderer-level attacker to break out of Chrome's security sandbox. Affected are all Chrome for Mac versions prior to 151.0.7922.137. Critically, this vulnerability is a second-stage exploit primitive - it requires the renderer process to already be compromised via a separate, chained vulnerability before this UAF can be weaponized for full sandbox escape. No public exploit code or CISA KEV listing has been identified at time of analysis.
Use-after-free in Chrome's V8 JavaScript engine (versions prior to 151.0.7922.137) enables remote code execution inside the browser sandbox when a victim visits a crafted HTML page. The vulnerability carries a CVSS 8.8 score reflecting its network-reachable, low-complexity attack path requiring only a single user interaction. No public exploit code or CISA KEV listing has been identified at time of analysis, though the Chromium security team rated severity as High and issued an emergency stable-channel update.
Heap and stack buffer overflow in CivetWeb's read_websocket() function (through commit 4a4f0c95) allows unauthenticated remote attackers to corrupt memory by sending crafted compressed WebSocket frames, but only against instances compiled with both USE_ZLIB and MG_EXPERIMENTAL_INTERFACES build flags. Attackers negotiate permessage-deflate during the WebSocket handshake and send an RSV1-flagged frame that triggers a 4-byte zlib sync trailer write past the allocated buffer boundary, corrupting heap metadata and enabling denial of service or potential code execution (per VulnCheck tagging). No public exploit code is confirmed and this CVE does not appear in CISA KEV at time of analysis, but the deterministic 4-byte overwrite primitive is a credible research target; the non-default build configuration substantially limits the real-world exploitable population.
MongoDB Server's query execution engine contains a use-after-free condition (CWE-416) that authenticated users with read and write privileges can trigger by running specific queries against time-series collections. The dereferencing of a freed internal pointer results in either a full server crash - denying service to all connected clients - or partial disclosure of freed heap memory contents within query results. No public exploit code exists and the vulnerability is not listed in the CISA KEV catalog at time of analysis, though the network-accessible, low-complexity attack path elevates practical urgency for deployments relying on time-series collections.
MongoDB Server's query subsystem contains a type confusion flaw (CWE-843) that allows any authenticated user holding read privileges to crash the server process by submitting a specially formed query filter, resulting in a denial of service. The CVSS 4.0 score of 7.1 with VA:H and PR:L reflects the realistic threat: any legitimate database user - including service accounts or compromised low-privilege credentials - can take the database offline with no attack complexity. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low exploitation bar warrants prompt patching once available.
Memory corruption in MongoDB Server's timeseries collection handling allows an authenticated user with write privileges to corrupt internal bucket data structures through crafted document insertions, then trigger out-of-bounds memory access via a subsequent insert. The impact spans denial of service via server crash, limited exposure of in-process memory contents, and memory corruption - all achievable without complex prerequisites beyond low-privilege authentication. No public exploit is identified at time of analysis, but the CVSS 4.0 score of 7.2 reflects the high availability impact against a widely deployed database platform.
Use-after-free in MongoDB Server's timeseries bucket lifecycle handling allows an authenticated user with write-level privileges to corrupt internal server memory, potentially crashing the server process or executing unintended code. The CVSS 4.0 score of 7.7 reflects a network-reachable vulnerability tempered by a low-privilege authentication requirement and a specific attack prerequisite (AT:P), indicating the flaw requires a particular lifecycle state in timeseries collections rather than a simple, reliable trigger. No public exploit code exists and this vulnerability has not been confirmed as actively exploited at time of analysis.
Use-after-free memory corruption in MongoDB Server's $graphLookup aggregation stage allows an authenticated high-privilege user to crash the server or potentially execute unintended code by combining aggregation and memory-management commands in a way that causes a stale internal reference to be dereferenced after the underlying memory is freed. Affected versions are MongoDB Server 8.3.0 through 8.3.7; a vendor-released patch is available in 8.3.8. No public exploit code or CISA KEV listing has been identified at time of analysis, making this a high-severity but access-gated vulnerability.
