CVE-2026-81633 MEDIUM PATCH This Month

Relay node query crash in AshGraphql (ash_graphql 0.27.0 through 1.10.x) allows an unauthenticated remote caller to abort the Absinthe node(id:...) resolver by supplying a base64-encoded relay ID whose type segment resolves to an existing BEAM VM atom that is not a registered relay resource type. Because the resolver calls Map.fetch!/2 before Absinthe's rescue handlers run, the resulting KeyError surfaces as an unhandled process exception rather than a structured GraphQL error, potentially leaking an internal stacktrace with module names and file paths. No public exploit code has been identified at time of analysis, though the fix commit is publicly visible on GitHub.

CVE-2026-82550 MEDIUM POC This Month

Improper input validation in the NGSetupRequest Handler of Linux Foundation Magma 1.9.0 allows remote unauthenticated attackers to impact availability of the 5G core's Access and Mobility Management Function (AMF) by supplying a malformed NG-IoT-DefaultPagingDRX argument. A public proof-of-concept is available via GitHub issue #16023, though the vulnerability has not been added to CISA KEV and the project maintainers have not responded to the coordinated disclosure, meaning no patch is available. The CVSS 4.0 score of 6.9 reflects limited availability impact only, with no confidentiality or integrity exposure.

CVE-2026-82648 HIGH This Week

SSRF filter bypass in WWBN AVideo exposes cloud metadata services and loopback interfaces to authenticated low-privilege attackers. The isSSRFSafeURL function fails to normalize IPv6 NAT64 addresses rendered in hexadecimal notation, allowing crafted URLs such as 64:ff9b::a9fe:a9fe to resolve to protected addresses like 169.254.169.254 while evading the SSRF blocklist. Exploitation could yield cloud instance credentials or access to internal services; no public exploit or KEV listing is confirmed at time of analysis.

CVE-2026-82639 HIGH This Week

Credential exfiltration in NextChat 2.15.8-2.16.1 allows unauthenticated network attackers to steal the server's OpenAI API key by exploiting flawed URL validation in the proxy endpoint. The x-base-url header is checked using substring matching rather than hostname parsing, so any URL containing the string 'api.openai.com' - including attacker-controlled domains like 'evil.attacker.com/api.openai.com' - passes validation and causes NextChat to forward the OpenAI API key in the Authorization header to the attacker's server. No public exploit identified at time of analysis, though a GitHub issue documenting the flaw is publicly accessible.

CVE-2026-55068 CRITICAL POC PATCH GHSA Act Now

NF registration poisoning in free5GC's Network Repository Function (NRF) lets attackers with SBI network access register forged Network Function profiles containing arbitrary, attacker-controlled service endpoint IPs, because the RegisterNFInstance handler performs no field validation against 3GPP TS 29.510. Legitimate NFs (AMF, SMF, AUSF, UDM, PCF, NSSF) then discover the fake profiles via NFDiscover and route control-plane signaling to the attacker, enabling interception, OAuth2 credential harvesting, and denial of service across the entire 5G core service mesh. Publicly available exploit code exists and the vendor has released a patch; the flaw is CWE-20 with a vendor CVSS 4.0 base score of 9.3 (Critical).

CVE-2026-59322 MEDIUM This Month

Unsafe header deserialization in Spring Integration's EmbeddedHeadersJsonMessageMapper exposes applications to header injection across all active release trains (5.5.x through 7.1.0). The decodeNativeFormat method constructs GenericMessage objects with MutableMessageHeaders populated directly from attacker-controlled JSON-deserialized header maps, bypassing sanitization by default in the constructor. Low-privileged network attackers who can submit crafted byte payloads to an affected consumer channel can manipulate message headers, yielding partial confidentiality, integrity, and availability impacts. No public exploit has been identified at time of analysis and this CVE is not listed in CISA KEV.

CVE-2026-54718 PHP HIGH POC PATCH GHSA This Week

Remote code execution in the Silverstripe Advanced Workflow module allows high-privileged authenticated CMS users to execute arbitrary PHP on the server by injecting a crafted payload into the workflow email template field. The vulnerability affects the `symbiote/silverstripe-advancedworkflow` Composer package across three version lines, with patches released as 6.4.5, 7.1.3, and 7.2.1. No public exploit tool or CISA KEV listing exists at time of analysis, but the GitHub Security Advisory (GHSA-39mm-rwm3-29jp) and accompanying PR test case explicitly document the injection technique, lowering the reproduction barrier for any attacker who reads the advisory.

Remote code execution in the Silverstripe userforms module allows any authenticated CMS author to inject PHP into the email recipient's subject field, which is evaluated server-side by the Silverstripe template engine during form submission email dispatch. Affected are composer package silverstripe/userforms versions below 6.4.9, 7.0.0-7.0.6, and 7.1.0, all of which pass the EmailSubject field through the template parser without sanitizing PHP-bearing localization tags. No CISA KEV listing and no standalone public exploit exist at time of analysis, though the patch PR documents the exact payload format, materially lowering the exploitation barrier for any attacker holding CMS credentials.

CVE-2026-81707 CRITICAL PATCH Act Now

Fingerprint-verification spoofing in jahlives openssl_encrypt before 1.4.9 lets attackers embed ANSI escape sequences in the email field of an imported identity document, rewriting the terminal line that displays a key fingerprint. A remote, unauthenticated attacker who delivers a crafted identity bundle via normal contact-exchange or keyserver flows can make the tool render a fraudulent fingerprint, defeating the out-of-band verification that guards against key-substitution (MITM) attacks. No public exploit is identified at time of analysis and it is not on CISA KEV.

The optional D-Bus crypto service in jahlives/openssl_encrypt 1.4.x before 1.4.9 exposes org.freedesktop.DBus.Properties.Set without polkit authorization or input validation, enabling any local system-bus user to persistently disable the root daemon. Setting MaxConcurrentOperations to zero or a negative value causes the concurrency gate to reject all subsequent cryptographic requests from the daemon; setting it to an arbitrarily large value or manipulating DefaultTimeout degrades stability in the opposite direction. No public exploit code has been identified at time of analysis, and the flaw is not listed in CISA KEV.
