Privilege escalation in Go's golang.org/x/net/idna package (all versions before 0.55.0) stems from ToASCII and ToUnicode accepting Punycode labels that decode to an ASCII-only label, so ToUnicode("xn--example-.com") returns "example.com" instead of an error. Applications that perform authorization checks on an ASCII hostname and then convert it to Unicode can be tricked into permitting a name that the direct check would have rejected. This is a library-level flaw (CVSS 9.6, scope-changed) reported by the Go team; there is no public exploit identified at time of analysis and EPSS is very low (0.04%, 14th percentile).
Net::CIDR::Lite before version 0.24 accepts CIDR mask values with extraneous leading zeros (such as '/00' or '/01'), causing them to parse identically to their unpadded equivalents ('/0' or '/1'). This permits attackers to bypass IP-based access control lists by supplying alternate representations of the same network prefix, potentially granting unauthorized access to restricted resources. The vulnerability affects all Perl installations using vulnerable versions of this library and is rated with CVSS 6.5 (moderate integrity and availability impact). No active exploitation has been confirmed by CISA, but the flaw is automatable and exploitable remotely without authentication.
Net::CIDR::Lite Perl module versions before 0.24 fail to properly validate IP address and CIDR mask inputs, allowing attackers to bypass IP-based access control lists by supplying malformed addresses that are re-encoded differently by the parser. Inputs with trailing newlines or non-ASCII digit characters pass validation but resolve to unintended IP addresses, causing find() and bin_find() functions to incorrectly match or miss addresses. This affects network security controls that rely on CIDR matching for authorization decisions.
Cache key collision in Mercure hub TopicSelectorStore enables authorization bypass through crafted topic names. Attackers can poison the match result cache by exploiting underscore-based key concatenation, causing private updates to be delivered to unauthorized subscribers or blocking legitimate deliveries. Affects Go package github.com/dunglas/mercure prior to version 0.22.0. Exploitation requires ability to subscribe to the hub or publish updates with specially crafted topic/selector combinations. No public exploit identified at time of analysis.
Policy parser vulnerability in xdg-dbus-proxy prior to 0.1.7 allows authenticated local users to bypass eavesdrop restrictions and intercept D-Bus messages by exploiting improper whitespace handling in policy rule parsing. The proxy fails to normalize eavesdrop policy directives, permitting attackers to craft malformed policies (e.g., eavesdrop ='true' with spacing variations) that evade the eavesdrop=true access control checks. No public exploit code has been identified at time of analysis.
Zscaler Client Connector on Windows contains an incorrect startup configuration that permits limited traffic to bypass inspection under rare circumstances, resulting in potential information disclosure and integrity compromise. The vulnerability affects all versions of the product and requires user interaction to exploit, with a CVSS score of 5.4 reflecting the combination of network-based attack vector, low complexity, and low impact on confidentiality and integrity. No evidence of active exploitation or public exploit code has been identified.
PowerShell Universal versions before 2026.1.4 contain an improper input validation vulnerability in the apps and endpoints configuration system that allows authenticated users with creation or modification permissions to inject malicious URL paths that override existing application or system routes. This vulnerability can result in unintended request routing where legitimate traffic is redirected to attacker-controlled endpoints, as well as denial of service conditions through route conflicts. The vulnerability requires high-level authentication privileges (PR:H) but has been formally documented in the ENISA EUVD database (EUVD-2026-12636) and poses a real risk to multi-tenant PowerShell Universal deployments where administrative controls may not be strictly enforced.
Parse Dashboard versions 7.3.0-alpha.42 through 9.0.0-alpha.7 improperly cache master keys and read-only master keys using identical cache identifiers, allowing authenticated users to obtain privilege escalation by retrieving cached credentials not intended for their access level under race conditions. An attacker with read-only dashboard access could retrieve the full master key, while regular users could access the read-only master key, compromising Parse Server security boundaries. The vulnerability requires low privileges and specific timing conditions but is fixed in version 9.0.0-alpha.8.
GitLab CE/EE versions 18.8 before 18.8.4 allow authenticated developers to obscure file modifications from the web interface through specially crafted changes. This vulnerability enables users with developer privileges to conceal their code alterations from visibility and review, potentially bypassing transparency controls. Currently no patch is available, and the issue requires user interaction to exploit.
Improper Validation of Unsafe Equivalence in punycode by the idna crate from Servo rust-url allows an attacker to create a punycode hostname that one part of a system might treat as distinct while. Rated medium severity (CVSS 5.1), this vulnerability is remotely exploitable. Public exploit code available and no vendor patch available.
