CVE-2026-63442 1 Opnsense 1 Core 2026-10-17 8.1 High
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.11, the unauthenticated WebGUI login usernamefld accepts carriage-return and line-feed characters that survive LOG_AUTH processing through syslog-ng-lockout.conf into the syslog-ng program destination feeding lockout_handler. The consumer's readline() processing treats an injected fragment as a separate authentication event and selects the first syntactically valid IP address from the forged line. An attacker with network access to the login page can forge failure events for another IP, causing that IP to be added to the sshlockout PF table and its active states to be killed, or forge accepted events that reset an attacker's own brute-force counter. This can block administrative, DNS, gateway, or monitoring addresses and can bypass password-guessing lockout without authentication. This issue is fixed in version 26.1.11.

CVE-2026-88172 1 Microsoft 5 365 Apps, Microsoft Office Ltsc 2021, Microsoft Office Ltsc 2024 and 2 more 2026-10-17 6.5 Medium
Out-of-bounds read in Microsoft Office Excel allows an unauthorized attacker to disclose information over a network.
CVE-2026-60008 1 Gitea 1 Gitea 2026-10-17 3.5 Low
Gitea's Jupyter notebook renderer inserts the notebook's language_info.name metadata into a CSS class attribute while disabling sanitization and rendering directly in the main document without an iframe sandbox. A malicious repository notebook can supply multiple CSS classes that create a viewport-covering overlay and intercept clicks when another user views it. The reported impact is UI redress; script execution was not demonstrated.
CVE-2026-83850 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-17 7.8 High
Heap-based buffer overflow in Microsoft Windows Search Component allows an authorized attacker to elevate privileges locally.
CVE-2026-55154 1 Espocrm 1 Espocrm 2026-10-17 5.4 Medium
EspoCRM is an open source customer relationship management application. Prior to 9.3.9, application/Espo/Tools/Export/Format/Csv/Processor.php, application/Espo/Tools/Export/Format/Xlsx/OpenSpoutProcessor.php, and application/Espo/Tools/Export/Format/Xlsx/PhpSpreadsheetProcessor.php inspect only the first byte in sanitizeCellValue(). An authenticated low-privileged user can store a free-text value whose formula trigger is preceded by whitespace or a control character, causing CSV or XLSX export to omit the leading single-quote formula-neutralization prefix. When a privileged user opens the exported file and accepts applicable spreadsheet security prompts, spreadsheet software can ignore the whitespace or control-character prefix and evaluate the cell as a formula, permitting outbound data disclosure and, on legacy configurations with DDE enabled, command execution. This issue is fixed in version 9.3.9.
CVE-2026-88188 1 Microsoft 21 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 18 more 2026-10-17 7.8 High

CVE-2026-19673 1 Zephyrproject 1 Zephyr 2026-10-17 7.1 High
ethernet_recv() in subsys/net/l2/ethernet/ethernet.c validates only that the first net_buf of a received frame holds a plain 14-byte struct net_eth_hdr. When the ethertype is 0x8100 and VLAN is enabled on the interface, the same buffer is reinterpreted as the 18-byte struct net_eth_vlan_hdr without re-checking the length: the VLAN TCI and the inner ethertype are read from offsets 14..17, past pkt->buffer->len, and hdr_len is raised to 18 so the subsequent net_buf_pull() removes more bytes than the buffer holds. A single unauthenticated frame of 14 to 17 bytes carrying the VLAN ethertype triggers this. No knowledge of the node's VLAN configuration is needed: net_eth_get_vlan_iface() returns the base interface for the priority tag 0, and a broadcast destination address satisfies the "frame is for me" test, so a 16-byte broadcast frame with ethertype 0x8100 and TCI 0x0000 reaches the pull. Nothing in the receive path enforces the 60-byte Ethernet minimum — the USB CDC ECM and CDC NCM gadget classes in particular hand host-supplied frames of any non-zero length straight to net_recv_data(). With assertions enabled, net_buf_simple_pull() asserts and the node panics. In a production build (assertions and CONFIG_NET_BUF_HARDENING off) the uint16_t buffer length underflows to 65534 and buf->data is advanced past the end of the fragment's storage, so every later parser reads far outside the buffer and any net_buf_add() on that fragment computes tailroom from the underflowed length. The result is a reliable remote denial of service and out-of-bounds access with information-disclosure and corruption potential. Only configurations built with CONFIG_NET_VLAN=y that have a VLAN enabled on the receiving Ethernet interface, and whose MAC does not strip VLAN tags in hardware (ETHERNET_HW_VLAN_TAG_STRIP), are affected. The fix rejects the frame before the tag is read, so hdr_len is thereafter either 14 or 18 with both sizes validated against pkt->buffer->len.

CVE-2026-111282 1 Driftregion 1 Iso14229 2026-10-17 8.2 High
Driftregion iso14229 before 0.10.1 contains an integer wraparound in Handle_0x38_RequestFileTransfer that lets unauthenticated attackers bypass the file path length check. Attackers can send a short RequestFileTransfer (SID 0x38) request with filePathAndNameLength 0xFFFC-0xFFFF, causing callbacks to read past the receive buffer, crashing targets or disclosing memory.
CVE-2026-110857 2 Gitpython-developers, Gitpython Project 2 Gitpython, Gitpython 2026-10-17 7.5 High
GitPython before 3.2.0 contains a remote code execution vulnerability that allows attackers to run commands because Git.ls_remote forwards URLs without check_unsafe_protocols validation. Attackers can supply ext:: remote-helper URLs to execute commands when git permits the ext transport, while merge_base and IndexFile.move also accept unguarded option injection.
CVE-2026-110660 1 Vgmstream 1 Vgmstream 2026-10-17 3.3 Low
vgmstream through r2117 contains a stack out-of-bounds read vulnerability in the G.722.1/Siren14 decoder in g7221_lib.c, whose bit reader refills without checking the data_u32 array end. Attackers can supply crafted .s14 or .sss files that drive decode_vector_quantized_mlt_indices() past the stack buffer during format detection, crashing the application.

CVE-2026-85821 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-17 6.5 Medium

CVE-2026-101023 1 Gitea 1 Gitea 2026-10-17 9.1 Critical
Gitea's OAuth2 token endpoint verified the signature and grant of a token submitted with the `refresh_token` grant type, but not that the token was a refresh token. An unexpired access token for the same OAuth2 application and grant could be exchanged for a new access token and refresh token. Whoever holds such an access token could keep access beyond the token's original lifetime.
