CVE-2026-44452 1 H2o 1 H2o 2026-07-17 5.9 Medium
h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 8dc37cb, when h2o receives a ClientHello message over TLS or QUIC and it contains a zero-length SNI extension, the h2o server runs over the zero-length hostname while trying to copy the hostname, assuming that it is NULL-terminated. This is a potential denial-of-service attack vector in sense that it might trigger segmentation violation. This issue has been fixed by commit 8dc37cb.
CVE-2026-60140 1 Automationdirect 1 Productivity Suite 2026-07-17 6.1 Medium
An out-of-bounds read vulnerability in the Productivity Suite allows a local attacker to trigger kernel memory corruption by sending a crafted IOCTL request. This can lead to exposing sensitive information or causing the affected product to become unstable or unavailable.
CVE-2026-57896 1 Automationdirect 1 Productivity Suite 2026-07-17 6.1 Medium
An out-of-bounds read vulnerability in the Productivity Suite allows a local attacker to trigger kernel memory corruption by sending a crafted IOCTL request. This could lead to limited information disclosure or disruption of the affected product.
CVE-2026-60073 1 Automationdirect 1 Productivity Suite 2026-07-17 5.9 Medium
An out-of-bounds read in the Productivity Suite allows a physical attacker to control the length of data sent to a USB device. This can lead to a system crash or disclosure of kernel memory.
CVE-2026-57075 1 Toddr 1 Yaml::syck 2026-07-17 9.1 Critical
YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via a signed-char lookup-table index in syck_base64dec. The base64 decoder in the bundled libsyck indexes the 256-entry static table b64_xtable with a signed char, so any !!binary byte >= 0x80 sign-extends to a negative index and reads before the table. The decoder receives the raw bytes of any !!binary node, a standard YAML type not gated by $LoadBlessed or $LoadCode, so it is reached on the default Load path. Any caller that runs Load or LoadFile on an untrusted document containing a !!binary scalar with a high-bit byte triggers the read, and the value read can surface in the decoded result.
CVE-2026-57077 1 Toddr 1 Yaml::syck 2026-07-17 7.7 High
YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via an unbounded newline scan in newline_len. In the bundled libsyck newline_len and is_newline dereference the scan pointer, and the following byte for a "\r\n" pair, with no NUL-terminator or bounds check. During block-scalar lexing at a document boundary the scan runs one byte past the heap lexer buffer. This is an incomplete fix of CVE-2025-11683, on a lexer path the earlier fix did not cover. Any caller that runs Load or LoadFile on an untrusted document with a block scalar at a document boundary reaches the over-read.
CVE-2026-16013 1 Liftoff-sr 1 Cipster 2026-07-17 5.3 Medium
A vulnerability has been found in liftoff-sr CIPster up to 632336d414ef708a542377c1aa8d6fdb7c70a760. Affected by this issue is the function CipAppPath::deserialize_symbolic of the file source/src/cip/cipepath.cc. Such manipulation leads to out-of-bounds read. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The name of the patch is 886a4d090e1c5b0475f0b1c2fe0606a8f0d6a519. A patch should be applied to remediate this issue.
CVE-2026-44436 1 H2o 1 Quicly 2026-07-17 7.5 High
Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 8b178e6, Quicly is vulnerable to a Denial of Service attack through connection state corruption. In QUIC Invariants, the maximum length of a Connection ID is 255 bytes, while QUIC version 1 further restricts the maximum to 20 bytes. Quicly implements QUIC version 1 and therefore its CID buffers are limited to 20 bytes. However, to be able to respond to unknown versions of QUIC, its packet decoder accepts Connection IDs of up to 255 bytes. As its CID buffers are merely 20 bytes long, Quicly must reject QUIC version 1 packets with Connection IDs longer than that. The command line tool bundled with Quicly has had that check, however the library itself lacked such enforcement. As a consequence, when used by applications that lack their own enforcement, the connection state becoming inconsistent to buffer overrun. Fortunately, the overflow stops within the allocated chunk of memory, but nevertheless, the bug leads to assertion failures. This issue has been fixed by commit 8b178e6.
CVE-2026-34150 1 Wazuh 1 Wazuh 2026-07-17 7.5 High
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager's analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing  {key: value}  patterns longer than 30 bytes that trigger a sprintf overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.
CVE-2026-28378 1 Grafana 2 Grafana, Grafana Enterprise 2026-07-17 3.1 Low
The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.
CVE-2026-42533 1 F5 2 Nginx Open Source, Nginx Plus 2026-07-17 8.1 High
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-58469 2 Gnu, Wget 2 Wget, Wget 2026-07-16 7.5 High
GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.
CVE-2026-55137 1 Microsoft 14 365 Apps, Excel 2016, Microsoft Office 365 For Mac and 11 more 2026-07-16 7.8 High
Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code locally.
CVE-2026-50682 1 Microsoft 7 Windows 10 21h2, Windows 10 22h2, Windows 11 24h2 and 4 more 2026-07-16 7.1 High
Out-of-bounds read in Windows Active Directory allows an authorized attacker to deny service over a network.
CVE-2026-47088 1 Cyrusimap 1 Cyrus Imap 2026-07-16 3.1 Low
An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is heap exposure in nested MIME comment parsing. An authenticated IMAP user could craft an email message containing an RFC 822 comment ending with a backslash. When parsing the message, the server would read past the message's end in memory, and read into the heap, returning the read content to the user.
CVE-2026-46377 1 Tomwright 1 Dasel 2026-07-16 6.2 Medium
Dasel is a command-line tool and library for querying, modifying, and transforming data structures. From 3.0.0 until 3.10.1, the escape sequence handler in (*Tokenizer).parseCurRune in selector/lexer/tokenize.go increments past a trailing backslash in a quoted string such as "\ or '\ and then reads p.src[pos] without a bounds check, allowing attacker-controlled selector strings to trigger a Go index-out-of-range panic. This issue is fixed in version 3.10.1.
CVE-2026-14461 1 Bitwizard 1 Mtr 2026-07-16 6.5 Medium
mtr is vulnerable to Out-of-bound read vulnerability in ipinfo_lookup() function. An attacker who can influence the TXT response used for AS lookups can trigger this bug by returning a DNS response that is larger than 512 bytes and uses a crafted compression pointer in the answer NAME field. ipinfo_lookup() function uses the length of the response as the end-of-message boundary for dn_expand() function. The result is a reliable crash. This issue exists in the mtr through version 0.96 and it was fixed in commit 48e1794414d338ce47abc0f27c25ade8788af9c3.
CVE-2026-51537 1 Eipstackgroup 1 Opener 2026-07-16 9.1 Critical
EIPStackGroup OpENer 2.3.0 (commit 76b95cf) has an out-of-bounds read issue in Connection Manager handling of ForwardOpen requests when processing short malformed packets. An attacker can send a valid ENIP outer frame carrying a malformed CIP ForwardOpen/LargeForwardOpen request, causing the parser to continue reading fields even when request data is insufficient. This issue is remotely triggerable via network traffic and does not require authentication.
