Improper Validation of Unsafe Equivalence in Input

CVE-2022-0675In certain situations it is possible for an unmanaged rule to exist on the target system that has the same comment as the rule specified in the manifest. This could allow for unmanaged rules to exist on the target system and leave the system in an unsafe state.
CVE-2026-39821The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".
CVE-2026-50090The Aqara Cloud OAuth Authorization Endpoint (open-cn.aqara.com/oauth/authorize) is vulnerable to a redirect bypass due to lax controls on domain matching, which is an instance of "CWE-1289: Improper Validation of Unsafe Equivalence in Input" and has an estimated CVSS of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N (9.3 Critical).
CVE-2024-422191Password 8 before 8.10.36 for macOS allows local attackers to exfiltrate vault items because XPC inter-process communication validation is insufficient.
CVE-2026-49942Net::CIDR::Set versions through 0.20 for Perl did not validate network masks.
The mask portion of a network mask could contain Unicode digits such as the Arabic-Indic One (U+0661), or non-digits, which were ignored. This could allow network masks to accept larger networks.
Leading zeros were also accepted, but treated as decimal instead of octal. This could lead to confusion about what networks are acceptable.
CVE-2024-45179An issue was discovered in za-internet C-MOR Video Surveillance 5.2401 and 6.00PL01. Due to insufficient input validation, the C-MOR web interface is vulnerable to OS command injection attacks. It was found out that different functionality is vulnerable to OS command injection attacks, for example for generating new X.509 certificates, or setting the time zone. These OS command injection vulnerabilities in the script generatesslreq.pml can be exploited as a low-privileged authenticated user to execute commands in the context of the Linux user www-data via shell metacharacters in HTTP POST data (e.g., the city parameter). The OS command injection vulnerability in the script settimezone.pml or setdatetime.pml (e.g., via the year parameter) requires an administrative user for the C-MOR web interface. By also exploiting a privilege-escalation vulnerability, it is possible to execute commands on the C-MOR system with root privileges.
CVE-2026-39972Mercure is a protocol for pushing data updates to web browsers and other HTTP clients in a battery-efficient way. Prior to 0.22.0, a cache key collision vulnerability in TopicSelectorStore allows an attacker to poison the match result cache, potentially causing private updates to be delivered to unauthorized subscribers or blocking delivery to authorized ones. The cache key was constructed by concatenating the topic selector and topic with an underscore separator. Because both topic selectors and topics can contain underscores, two distinct pairs can produce the same key. An attacker who can subscribe to the hub or publish updates with crafted topic names can exploit this to bypass authorization checks on private updates. This vulnerability is fixed in 0.22.0.
CVE-2026-27610Parse Dashboard is a standalone dashboard for managing Parse Server apps. In versions 7.3.0-alpha.42 through 9.0.0-alpha.7, the `ConfigKeyCache` uses the same cache key for both master key and read-only master key when resolving function-typed keys. Under specific timing conditions, a read-only user can receive the cached full master key, or a regular user can receive the cached read-only master key. The fix in version 9.0.0-alpha.8 uses distinct cache keys for master key and read-only master key. As a workaround, avoid using function-typed master keys, or remove the `agent` configuration block from your dashboard configuration.
CVE-2026-34080xdg-dbus-proxy is a filtering proxy for D-Bus connections. Prior to 0.1.7, a policy parser vulnerability allows bypassing eavesdrop restrictions. The proxy checks for eavesdrop=true in policy rules but fails to handle eavesdrop ='true' (with a space before the equals sign) and similar cases. Clients can intercept D-Bus messages they should not have access to. This vulnerability is fixed in 0.1.7.
CVE-2026-49940Net::CIDR::Set versions through 0.20 for Perl accept non-ASCII IP addresses and netmasks.
Unicode digits such as the Arabic-Indic One (U+0661) were accepted but not properly parsed as numbers. This could allow network masks to accept larger networks.
CVE-2026-45191Net::CIDR::Lite versions before 0.24 for Perl does not properly consider extraneous zero characters in CIDR mask values, which may allow IP ACL bypass.
Mask forms like "/00" and "/01" pass validation and parse to the same prefix as their unpadded value.

CVE-2026-45190Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass.
Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result.
Example:
my $cidr = Net::CIDR::Lite->new();
$cidr->add("::1\n/128");
$cidr->find("::1a"); # incorrectly returns true

CVE-2024-45308HedgeDoc is an open source, real-time, collaborative, markdown notes application. When using HedgeDoc 1 with MySQL or MariaDB, it is possible to create notes with an alias matching the ID of existing notes. The affected existing note can then not be accessed anymore and is effectively hidden by the new one. When the freeURL feature is enabled (by setting the `allowFreeURL` config option or the `CMD_ALLOW_FREEURL` environment variable to `true`), any user with the appropriate permissions can create a note with an arbitrary alias, e.g. by accessing it in the browser. When MySQL or MariaDB are used, it is possible to create a new note with an alias that matches the lower-cased ID of a different note. HedgeDoc then always presents the new note to users, as these databases perform case-insensitive matching and the lower-cased alias is found first. This issue only affects HedgeDoc instances that use MySQL or MariaDB. Depending on the permission settings of the HedgeDoc instance, the issue can be exploited only by logged-in users or by all (including non-logged-in) users. The exploit requires knowledge of the ID of the target note. Attackers could use this issue to present a manipulated copy of the original note to the user, e.g. by replacing the links with malicious ones. Attackers can also use this issue to prevent access to the original note, causing a denial of service. No data is lost, as the original content of the affected notes is still present in the database. Users are advised to upgrade to version 1.10.0 which addresses this issue. Users unable to upgrade may disable freeURL mode which prevents the exploitation of this issue. The impact can also be limited by restricting freeURL note creation to trusted, logged-in users by enabling `requireFreeURLAuthentication`/`CMD_REQUIRE_FREEURL_AUTHENTICATION`.
CVE-2026-3563Improper input validation in the apps and endpoints configuration in PowerShell Universal before 2026.1.4 allows an authenticated user with permissions to create or modify Apps or Endpoints to override existing application or system routes, resulting in unintended request routing and denial of service via a conflicting URL path.
