CVE-2026-33555 (GCVE-0-2026-33555)
Vulnerability from cvelistv5 – Published: 2026-04-13 00:00 – Updated: 2026-04-22 18:43

VEX
Summary
An issue was discovered in HAProxy before 3.3.6. The HTTP/3 parser does not check that the received body length matches a previously announced content-length when the stream is closed via a frame with an empty payload. This can cause desynchronization issues with the backend server and could be used for request smuggling. The earliest affected version is 2.6.

Summary
A vulnerability has been identified in SICAM SIAPP SDK (All versions < V2.1.7). The SICAM SIAPP SDK server component does not enforce maximum length checks on certain variables before use. This could allow an attacker to send an oversized input that could trigger a stack overflow crashing the process and potentially causing denial of service.

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

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.

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.
