CVE-2026-42008 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 4.3 Medium
Forwarding information received from a host listed as a trusted proxy is not kept separate from Dovecot's own authentication fields, so a value sent by that host can be injected as an internal authentication field. Any host permitted to act as a trusted proxy can authenticate as any user without knowing that user's password. This affects deployments whose password database honours a field that permits authentication without a password. Deployments that do not configure trusted proxies are not affected. Restrict the list of trusted proxy networks to hosts that are fully under your control. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-42391 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 7.5 High
An unauthenticated attacker can send an IMAP ID command with a very large number of parameters before logging in, which causes memory and CPU usage to grow disproportionately. The login process can be terminated by the out-of-memory handling, which also terminates all other connections handled by the same process. This can cause degradation or denial of service for IMAP logins. Limit the number of connections handled by a single imap-login process. This has a performance impact though. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-51740 1 Totolink 1 T6 2026-09-01 9.8 Critical

Incorrect access control in the delStaticDhcpRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to remove static DHCP reservations via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-42392 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 4.3 Medium
An attacker that has valid credentials can send an invalid IMAP URLFETCH command, which causes uninitialized memory to be included in the error response returned to the client. Process memory contents can be disclosed to the client, which may include sensitive data. Disable the IMAP URLAUTH functionality. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-51717 1 Totolink 1 T6 2026-09-01 9.1 Critical
Incorrect access control in the setOpModeCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to change the device operating mode via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-51716 1 Totolink 1 T6 2026-09-01 7.5 High
Incorrect access control in the delPortForwardRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to delete port-forwarding rules via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-51711 1 Totolink 1 T6 2026-09-01 9.1 Critical
Incorrect access control in the setWiFiWpsStart function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to open a wireless pairing window via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-51710 1 Totolink 1 T6 2026-09-01 9.1 Critical
Incorrect access control in the setParentalRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to alter parental-control behavior via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-42393 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 3.1 Low
The comparison used for the doveadm password and API key is not fully timing safe and can reveal the length of the configured secret. An attacker with access to the same network as the doveadm service, able to make repeated requests and measure response timing accurately, can learn the length of the secret, which reduces the effort needed to guess it. The secret value itself is not disclosed. Restrict network access to the doveadm service to trusted clients. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-51709 1 Totolink 1 T6 2026-09-01 9.8 Critical
Incorrect access control in the setWiFiBasicCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to reconfigure primary Wi-Fi settings via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-51701 1 Totolink 1 T6 2026-09-01 9.1 Critical
Incorrect access control in the setMacFilterRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to change device access control via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
CVE-2026-51152 1 Qd 1 Qd 2026-09-01 9.1 Critical
Server-side request forgery (SSRF) in the /har/test endpoint in QD 20220208 through 20250803. Fetcher.build_request() in libs/fetcher.py constructs an httpclient.HTTPRequest from user-supplied JSON without validating URL scheme, host, or IP range. The /har/test handler does not require authentication, enabling unauthenticated remote attackers to force the QD server to send arbitrary HTTP requests to internal network resources and cloud metadata endpoints. validate_cert is set to False, disabling TLS verification.
CVE-2026-42395 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 4.3 Medium
A host listed as a trusted proxy can send forwarding information containing a NUL byte, which crashes the login process on the following login attempt. The login process is terminated, which can cause degradation or denial of service for logins. Deployments that do not configure trusted proxies are not affected. Restrict the list of trusted proxy networks to hosts that are fully under your control. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-52681 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 3.1 Low
Sieve CPU resource usage is tracked in the compiled script, so an attacker that has valid credentials can reset the accounting by repeatedly changing the active script. Compiled script files are also not removed when a script is deleted or renamed. The configured Sieve CPU limit can be bypassed, allowing sustained CPU consumption, and the leftover files increase disk consumption. Both can cause degradation of service for mail delivery. Monitor system for abnormal CPU usage and disk consumption. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-19032 1 Fasterxml 1 Jackson-databind 2026-09-01 5.3 Medium
jackson-databind's deserializer for java.nio.file.Path resolves an attacker-supplied URI without restricting the URI scheme. In JDKFromStringDeserializer.NioPathHelper.deserialize, a string bound from untrusted JSON is passed to new URI(value) and then to Path.of(uri). When that throws FileSystemNotFoundException, the code enumerates ServiceLoader<FileSystemProvider> and calls provider.getPath(uri) on the first provider whose scheme matches the attacker-chosen scheme. Untrusted JSON can therefore select and drive an arbitrary registered FileSystemProvider during readValue under a default JsonMapper, and forces provider class loading at the same time. With only the JDK built-in providers (file, jar/zipfs) present, the resolved path is inert and no mount or network I/O occurs; further impact requires a side-effecting third-party FileSystemProvider on the classpath. This affects com.fasterxml.jackson.core:jackson-databind from 2.8.0 before 2.18.10, from 2.19.0 before 2.21.6, and from 2.22.0 before 2.22.2, and tools.jackson.core:jackson-databind from 3.0.0 before 3.1.6 and from 3.2.0 before 3.2.2. Users should upgrade to 2.18.10, 2.21.6, 2.22.2, 3.1.6, or 3.2.2. Binding java.nio.file.Path from untrusted JSON should be avoided regardless of version.
CVE-2026-52687 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 6.5 Medium
An attacker that has valid credentials can select a compression algorithm for the IMAP connection whose decompression state requires a large amount of memory, and open several such connections. The memory limit of the process is reached with only a few connections, terminating the process and all connections it handles, which can cause degradation or denial of service for IMAP. Disable IMAP compression. Alternatively limit the number of connections handled by a single imap-login process, though this has a performance impact. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-14697 1 Zephyrproject 1 Zephyr 2026-09-01 6.5 Medium
net_ipv6_send_ns() in subsys/net/ip/ipv6_nbr.c allocates a transmit net_pkt for a Neighbor Solicitation. When it is called with a data packet pending on an unresolved neighbor and that neighbor's pending_queue is already non-empty (an NS is already outstanding), the function appends the data packet and returns early without ever sending the NS via net_send_data() or releasing it with net_pkt_unref(). The freshly allocated NS net_pkt and its attached TX buffers are held only by a local variable and are leaked permanently, never returning to CONFIG_NET_PKT_TX_COUNT / CONFIG_NET_BUF_TX_COUNT. The leaking branch sits on the normal IPv6 transmit path: net_ipv6_prepare_for_send() (called from net_if.c) invokes net_ipv6_send_ns() for any outbound or forwarded IPv6 packet whose next hop is not yet in the neighbor cache. An on-link (adjacent) attacker can drive it deterministically by sending a burst of request packets (for example ICMPv6 echo requests or UDP datagrams) that all spoof a single non-existent on-link source address: the node generates a reply to each, the first reply queues an NS, and every subsequent reply during the roughly three-second INCOMPLETE resolution window takes the leaking branch and loses one TX packet. Router-configured nodes forwarding attacker traffic toward a non-existent on-link host leak identically. Because the leaked packets are never reclaimed and CONFIG_NET_PKT_TX_COUNT defaults to only 4 (14 for Ethernet), a brief low-rate burst exhausts the TX pool. Once exhausted the node can no longer allocate any transmit packet and cannot send TCP/UDP, ARP/ND, or any reply at all, producing a complete and persistent network denial of service that does not self-heal until reboot. The fix releases the unsent NS packet with net_pkt_unref(pkt) before the early return.
