CVE-2026-25704 1 Pop-os 1 Cosmic-greeter 2026-04-16 N/A
A Privilege Dropping / Lowering Errors/Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in  cosmic-greeter can allow an attacker to regain privileges that should have been dropped and abuse them in the racy checking logic. This issue affects cosmic-greeter before https://github.Com/pop-os/cosmic-greeter/pull/426.
CVE-2026-27127 1 Craftcms 2 Craft Cms, Craftcms 2026-04-16 6.3 Medium
Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through 5.8.22, the SSRF validation in Craft CMS’s GraphQL Asset mutation performs DNS resolution separately from the HTTP request. This Time-of-Check-Time-of-Use (TOCTOU) vulnerability enables DNS rebinding attacks, where an attacker’s DNS server returns different IP addresses for validation compared to the actual request. This is a bypass of the security fix for CVE-2025-68437 that allows access to all blocked IPs, not just IPv6 endpoints. Exploitation requires GraphQL schema permissions for editing assets in the `<VolumeName>` volume and creating assets in the `<VolumeName>` volume. These permissions may be granted to authenticated users with appropriate GraphQL schema access and/or Public Schema (if misconfigured with write permissions). Versions 4.16.19 and 5.8.23 patch the issue.
CVE-2026-3383 1 Chaiscript 1 Chaiscript 2026-04-16 3.3 Low
A weakness has been identified in ChaiScript up to 6.1.0. This affects the function chaiscript::Boxed_Number::go of the file include/chaiscript/dispatchkit/boxed_number.hpp. Executing a manipulation can lead to divide by zero. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-31827 1 Blue-b 1 Alienbin 2026-04-16 N/A
Alienbin is an anonymous code and text sharing web service. In 1.0.0 and earlier, the /save endpoint in server.js drops and recreates the MongoDB TTL index on the entire post collection for every new paste submission. When User B submits a paste with a short TTL (e.g., 30 seconds), the TTL index is recreated with expireAfterSeconds: 30 for all documents in the collection. This causes User A's paste (originally set to 7 days) to be deleted after 30 seconds. An attacker can intentionally delete all existing pastes by repeatedly submitting pastes with ttlOption=30s.
CVE-2026-20438 2 Google, Mediatek 12 Android, Mt2718, Mt6899 and 9 more 2026-04-16 6.4 Medium
In MAE, there is a possible out of bounds write due to a race condition. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10431920; Issue ID: MSV-5835.
CVE-2026-20445 2 Google, Mediatek 24 Android, Mt6835, Mt6855 and 21 more 2026-04-16 4.4 Medium
In MDDP, there is a possible system crash due to a race condition. This could lead to local denial of service if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10289875; Issue ID: MSV-5184.
CVE-2026-20057 1 Cisco 3 Cisco Utd Snort Ips Engine Software, Cyber Vision, Secure Firewall Threat Defense 2026-04-16 5.8 Medium
Multiple Cisco products are affected by a vulnerability in the Snort 3 Visual Basic for Applications (VBA) feature which could allow an unauthenticated, remote attacker to cause the Snort 3 Detection Engine to crash.&nbsp; &nbsp; This vulnerability is due to lack of proper error checking when decompressing VBA data. An attacker could exploit this vulnerability by sending a crafted VBA data to the Snort 3 Detection Engine on the targeted device. A successful exploit could allow the attacker to cause the Snort 3 Detection Engine to unexpectedly restart causing a a denial of service (DoS) condition.
CVE-2026-28550 1 Huawei 1 Harmonyos 2026-04-16 4 Medium

Race condition vulnerability in the maintenance and diagnostics module. Impact: Successful exploitation of this vulnerability may affect availability.
CVE-2026-28551 1 Huawei 1 Harmonyos 2026-04-16 4.7 Medium
Race condition vulnerability in the device security management module. Impact: Successful exploitation of this vulnerability may affect availability.
CVE-2026-27750 2 Avira, Gen Digital 3 Avira Internet Security Suite, Internet Security, Avira Internet Security 2026-04-16 7.8 High
Avira Internet Security contains a time-of-check time-of-use (TOCTOU) vulnerability in the Optimizer component. A privileged service running as SYSTEM identifies directories for cleanup during a scan phase and subsequently deletes them during a separate cleanup phase without revalidating the target path. A local attacker can replace a previously scanned directory with a junction or reparse point before deletion occurs, causing the privileged process to delete an unintended system location. This may result in deletion of protected files or directories and can lead to local privilege escalation, denial of service, or system integrity compromise depending on the affected target.
CVE-2026-28789 1 Olivetin 1 Olivetin 2026-04-16 7.5 High
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.3, an unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow. Concurrent requests to /oauth/login can trigger unsynchronized access to a shared registeredStates map, causing a Go runtime panic (fatal error: concurrent map writes) and process termination. This allows remote attackers to crash the service when OAuth2 is enabled. This issue has been patched in version 3000.10.3.
CVE-2026-2753 1 Navtor 1 Navbox 2026-04-16 7.5 High
An Absolute Path Traversal vulnerability exists in Navtor NavBox. The application exposes an HTTP service that fails to properly sanitize user-supplied path input. Unauthenticated remote attackers can exploit this issue by submitting requests containing absolute filesystem paths. Successful exploitation allows the attacker to retrieve arbitrary files from the underlying filesystem, limited only by the privileges of the service process. This can lead to the exposure of sensitive configuration files and system information.
CVE-2026-26017 1 Coredns.io 1 Coredns 2026-04-16 7.7 High
CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a logical vulnerability in CoreDNS allows DNS access controls to be bypassed due to the default execution order of plugins. Security plugins such as acl are evaluated before the rewrite plugin, resulting in a Time-of-Check Time-of-Use (TOCTOU) flaw. This issue has been patched in version 1.14.2.
CVE-2026-28689 1 Imagemagick 1 Imagemagick 2026-04-16 6.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain="path" authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
CVE-2026-31824 1 Sylius 1 Sylius 2026-04-16 8.2 High
Sylius is an Open Source eCommerce Framework on Symfony. A Time-of-Check To Time-of-Use (TOCTOU) race condition was discovered in the promotion usage limit enforcement. The same class of vulnerability affects the promotion usage limit (the global used counter on Promotion entities), coupon usage limit (the global used counter on PromotionCoupon entities), and coupon per-customer usage limit (the per-customer redemption count on PromotionCoupon entities). In all three cases, the eligibility check reads the used counter (or order count) from an in-memory Doctrine entity during validation, while the actual usage increment in OrderPromotionsUsageModifier happens later during order completion — with no database-level locking or atomic operations between the two phases. Because Doctrine flushes an absolute value (SET used = 1) rather than an atomic increment (SET used = used + 1), and because the affected entities lack optimistic locking, concurrent requests all read the same stale usage counts and pass the eligibility checks simultaneously. An attacker can exploit this by preparing multiple carts with the same limited-use promotion or coupon and firing simultaneous PATCH /api/v2/shop/orders/{token}/complete requests. All requests pass the usage limit checks and complete successfully, allowing a single-use promotion or coupon to be redeemed an arbitrary number of times. The per-customer limit can be bypassed in the same way by a single customer completing multiple orders concurrently. No authentication is required to exploit this vulnerability. This may lead to direct financial loss through unlimited redemption of limited-use promotions and discount coupons. The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 and above.
