|---|---|---|---|---|
| 7.8 high | CVE-2026-83549 KEV | SonicWall SMA1000 Post-authentication Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. | 11% | 2 Sept 2026 |
| 10.0 critical | CVE-2026-83548 KEV | SonicWall SMA1000 A Pre-authentication SSRF vulnerability exists in the SMA1000 Appliance Work Place interface due to an unintended alternate access path. A remote unauthenticated attacker could potentially exploit this vulnerability to gain unauthorized access to sensitive functionality and perform unauthorized operations. | 8.8% | 2 Sept 2026 |
| 9.8 critical | CVE-2026-82329 KEV | jfrog artifactory JFrog Artifactory contains an authentication weakness that, under default configuration, may allow an unauthenticated attacker with network access to obtain administrative privileges. | 14% | 2 Sept 2026 |
| 9.3 critical | CVE-2026-9586 KEV | Sangoma Switchvox SMB Edition An unauthenticated SQL injection vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The /pa endpoint processes XML content beginning with <PolycomIPPhone> and directly concatenates the user-controlled PhoneIP value into PostgreSQL queries without sanitization or parameterization. An unauthenticated remote attacker can execute arbitrary SQL statements against the backend PostgreSQL database using a single crafted request, including database operations and remote code execution. | 19% | 2 Sept 2026 |
| 8.8 high | CVE-2026-59822 KEV | BerriAI litellm LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.84.0, LiteLLM's MCP Streamable HTTP endpoint allowed an unauthenticated attacker to use a fabricated Authorization header to trigger an OAuth2 passthrough fallback path that replaced failed LiteLLM key validation with an empty UserAPIKeyAuth() object, allowing requests to reach MCP tooling without a valid LiteLLM key. This issue is fixed in version 1.84.0. | 0.84% | 2 Sept 2026 |
| 10.0 critical | CVE-2026-49869 KEV | kestra-io kestra Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, AuthenticationFilter in Kestra OSS uses request.getPath().endsWith("/configs") to whitelist the public configuration endpoint from Basic Auth. Because the check is a suffix match rather than an exact path match, any API path whose last segment is configs bypasses authentication entirely. An unauthenticated remote attacker can exploit this to create and execute arbitrary workflows without credentials. Because Kestra ships with script execution plugins (plugin-script-shell, plugin-script-python, etc.) enabled by default, this directly results in unauthenticated Remote Code Execution as root inside the Kestra worker container. This vulnerability is fixed in 1.0.45 and 1.3.21. | 2.1% | 2 Sept 2026 |
| 6.5 medium | CVE-2026-48710 KEV | Kludex starlette Starlette is a lightweight ASGI framework/toolkit. Prior to version 1.0.1, the HTTP `Host` request header was not validated before being used to reconstruct `request.url`. Because the routing algorithm relies on the raw HTTP path while `request.url` is rebuilt from the `Host` header, a malformed header could make `request.url.path` differ from the path that was actually requested. Middleware and endpoints that apply security restrictions based on `request.url` (rather than the raw `scope` path) could therefore be bypassed. Users should upgrade to a version greater than or equal to version 1.0.1, which validates the `Host` header against the grammar of RFC 9112 §3.2 / RFC 3986 §3.2.2 when constructing `request.url` and falls back to `scope["server"]` for malformed values. | 7.1% | 2 Sept 2026 |
| 9.4 critical | CVE-2026-82078 KEV | PaperCut MF/NG An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG. The application instantiates database driver classes based on configurable driver names without validating against an allowlist of approved drivers. If an attacker can manipulate system configuration parameters, this enables the execution of arbitrary Java bytecode residing on the application classpath under the security context of the PaperCut server process. | 61% | 31 Aug 2026 |
| 8.8 high | CVE-2026-81578 KEV | PaperCut MF/NG An improper access control vulnerability exists in the web management interface of PaperCut MF and PaperCut NG. Under specific conditions, unauthenticated remote requests targeting administrative functions can trigger backend actions prior to the completion of access validation checks. This allows an unauthenticated remote attacker to modify certain system configurations. | 85% | 31 Aug 2026 |
| 5.3 medium | CVE-2026-66384 KEV | jfrog artifactory An authenticated user may write data outside the intended Docker cache path under specific remote-repository conditions. | 0.66% | 27 Aug 2026 |
| 7.8 high | CVE-2026-53362 KEV | Linux In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check. | 0.71% | 27 Aug 2026 |
| 9.8 critical | CVE-2023-49105 KEV | owncloud server An issue was discovered in ownCloud owncloud/core before 10.13.1. An attacker can access, modify, or delete any file without authentication if the username of a victim is known, and the victim has no signing-key configured. This occurs because pre-signed URLs can be accepted even when no signing-key is configured for the owner of the files. The earliest affected version is 10.6.0. | 43% | 27 Aug 2026 |
| 8.8 high | CVE-2026-8452 KEV | NetScaler ADC Memory overflow vulnerability NetScaler ADC and NetScaler Gateway leading to unpredictable or erroneous behavior and Denial of Service if the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server | 1.0% | 26 Aug 2026 |
