CVE-2026-18397 (GCVE-0-2026-18397)

Vulnerability from cvelistv5 – Published: 2026-10-01 21:49 – Updated: 2026-10-02 19:42
VLAI
Title
SConnect: Native Host Unauthenticated Remote Code Execution Vulnerability
Summary
This vulnerability enables unauthenticated remote code execution (RCE) on a victim's machine by exploiting a combination of cryptographic weaknesses and memory management issues in the SConnect native host component. The attack leverages an unrestricted messaging interface between an attacker-controlled web page and the native host, allowing malicious input to bypass security checks.

CVE-2026-14587 (GCVE-0-2026-14587)

Vulnerability from cvelistv5 – Published: 2026-08-05 16:10 – Updated: 2026-08-05 18:41
VLAI
Title
Unathenticated connection can hold Bolt channel open
Summary
Neo4j's Bolt modern handshake decoder treats an overlong capability bit mask the same way it treats a truncated bit mask. When an unauthenticated client sends a selected protocol version followed by 32 continuation bytes in the capability mask, the decoder resets the reader index and waits for more bytes instead of rejecting the protocol message and closing the channel. Because the same unread bytes remain at the front of the decoder buffer, appending a terminating byte later does not recover the connection. The decoder re-reads the same first 32 continuation bytes, returns without producing a handshake-finalization message, and leaves the channel open. This can be triggered before authentication by any client that can reach the Bolt connector.

CVE-2026-6432 (GCVE-0-2026-6432)

Vulnerability from cvelistv5 – Published: 2026-06-25 13:49 – Updated: 2026-10-15 13:52

Title
Improper bounds validation in EmberZNet SDK
Summary
Improper bounds validation in the ZAP command parser of EmberZNet SDK versions 8.0.0 through 9.1.1 (inclusive) and before 7.5.2 (exclusive) may result in crashes or dynamic memory leakage. In order to exploit this vulnerability, an attacker would have to have the ability to send arbitrary messages on the network. The only known exploit of this vulnerability leaks a limited number of bytes from the stack. No denial-of-service, memory corruption, or remote code execution has been shown.

CVE-2026-5766 (GCVE-0-2026-5766)

Vulnerability from cvelistv5 – Published: 2026-05-05 14:49 – Updated: 2026-05-06 15:25

Title
Potential denial-of-service vulnerability in ASGI requests via file upload limit bypass
Summary
An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. ASGI requests with a missing or understated `Content-Length` header can bypass the `FILE_UPLOAD_MAX_MEMORY_SIZE` limit, potentially loading large files into memory and causing service degradation. As a reminder, Django expects a limit to be configured at the web server level rather than solely relying on `FILE_UPLOAD_MAX_MEMORY_SIZE`. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Kyle Agronick for reporting this issue.

Title
Buffer overflow in Bluetooth Mesh SDK when handling extended advertisements
Summary
In Bluetooth Mesh SDK 6.1.4 and earlier, malformed extended advertisements can trigger out-of-bounds writes leading to stack corruption and remote code execution. These messages must come from a device that has already joined the network. Only provisioners supporting extended advertisements may be impacted.

Mitigation
Implementation

When processing structured incoming data containing a size field followed by raw data, ensure that you identify and resolve any inconsistencies between the size field and the actual size of the data.

Mitigation
Implementation

Do not let the user control the size of the buffer.

Mitigation
Implementation

Validate that the length of the user-supplied data is consistent with the buffer size.

CAPEC-47: Buffer Overflow via Parameter Expansion

In this attack, the target software is given input that the adversary knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
