CVE-2026-87726
LowCVSS 3.9Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
Insufficient API bounds checking in phalFelica in NXP NXPNfcRdLib RC663 through 07.14.00_Pub may allow an attacker with privileges or an untrusted third party to access unintended memory regions, potentially leading to limited loss of confidentiality, integrity, and availability. All software versions from 07.18.00 onwards have fixed this problem.
Risk Assessment
An attacker may access sensitive data in memory, compromising confidentiality and integrity. This could also lead to crashes or malfunction of the device.
Recommendation
Update NXP NXPNfcRdLib software to version 07.18.00 or later, which includes the fix. Restrict physical and logical access to devices using this library.

- CVE-2026-59107Critical
A security vulnerability has been identified in the vSolution Matrix file sharing feature. A shared cryptographic trust configuration could allow an attacker who obtains the matching private key to authenticate to an affected device via SSH as root. This vulnerability affects only devices configured as a vSolution Matrix main/master station with the file sharing feature enabled.
- CVE-2026-59106Critical
A security vulnerability has been identified in the WolfProt interface implementation. Insufficient neutralization of user-controlled input could allow an unauthenticated attacker with network access to a vulnerable service to execute operating-system commands with the privileges of the affected application service.
- CVE-2026-116485Critical
danmu_api before 1.21.7 contains an authentication bypass vulnerability that allows unauthenticated attackers to modify server environment configuration when the default TOKEN is used and ADMIN_TOKEN is unset. Attackers can send POST requests to /api/env/set, /api/env/add, or /api/env/del to set ADMIN_TOKEN, lock out operators, redirect OTHER_SERVER or PROXY_URL for SSRF, and trigger redeployment.
- CVE-2026-116214Critical
MacCMS v10 before 2026.1000.4054 contains an authentication bypass vulnerability that allows unauthenticated attackers to reset any member's password because check_msg() never compares msg_to. Attackers can request a recovery code to their own mailbox via user/findpass_msg, then submit it to user/findpass_reset with the victim's email or phone to take over the account.
- CVE-2026-115693Critical
Improper Certificate Validation vulnerability in hackney_ssl in benoitc hackney allows an on-path attacker to impersonate a server pinned to a private certificate authority via a certificate chain that ends in a publicly trusted root. hackney adds {partial_chain, fun hackney_ssl:partial_chain/1} to every verify_peer configuration, which accepts any certificate in the peer chain whose public key matches a root in the bundled certifi store, even when the connection is pinned to a private CA. The hostname check still applies, so the attacker needs a publicly trusted certificate for the pinned hostname. This issue affects hackney from 1.24.0 before 4.9.0.
- CVE-2026-115188Critical
An unrestricted file upload vulnerability exists in the campaign import feature of Mautic 7. When processing an uploaded campaign archive, the application copies the bundled asset files into a publicly accessible media directory without restricting their file names or types. An authenticated user with permission to create campaign imports can place arbitrary files, including server-side scripts, in the web root, leading to remote code execution on servers such as the default Apache setup of the official Mautic Docker image.
- CVE-2026-110475Critical
This vulnerability exists in the CreditNirvana Collections Platform due to improper authentication and authorization controls at the platform login service. An unauthenticated remote attacker could manipulate authentication requests and access APIs without a valid authenticated session. Successful exploitation could allow the attacker to enumerate platform users, establish sessions as arbitrary users including administrative users, and access and modify sensitive information.
- CVE-2026-107656Critical
An authentication bypass using an alternate path or channel vulnerability in Fortinet FortiSandbox 5.0.0 through 5.0.6, 4.4.0 through 4.4.9, 4.2 all versions, FortiSandbox PaaS 5.0.0 through 5.0.6, 4.4 all versions, and 4.2 all versions may allow an attacker to execute unauthorized code or commands via crafted HTTP requests.
- CVE-2026-116235Critical
A flaw was found in Oray Pugongying X5 Pro 7.6.1 in an unknown function of the L2TP Authentication component. Manipulating the Username argument causes CRLF injection. The attack can be launched remotely and a public exploit is available.
- CVE-2026-116234Critical
A vulnerability was detected in Oray Pugongying X5 Pro 7.6.1 in an unknown function of /etc/ipsec.conf within the IPsec Policy Handler component. Manipulating the secproto argument results in CRLF injection. The attack can be launched remotely and the exploit is public.
