CVE-2026-33732 WRITEUP MEDIUM
srvx is vulnerable to middleware bypass via absolute URI in request line
srvx is a universal server based on web standards. Prior to version 0.11.13, a pathname parsing discrepancy in srvx's `FastURL` allows middleware bypass on the Node.js adapter when a raw HTTP request uses an absolute URI with a non-standard scheme (e.g. `file://`). Starting in version 0.11.13, the `FastURL` constructor now deopts to native `URL` for any string not starting with `/`, ensuring consistent pathname resolution.
CVSS 4.8
CVE-2026-4867 WRITEUP HIGH
path-to-regexp vulnerable to Regular Expression Denial of Service via multiple route parameters
Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period (.). For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two parameters. With three or more, the generated lookahead does not block single separator characters, so capture groups overlap and cause catastrophic backtracking. Patches: Upgrade to [email protected] Custom regex patterns in route definitions (e.g., /:a-:b([^-/]+)-:c([^-/]+)) are not affected because they override the default capture group. Workarounds: All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change /:a-:b-:c to /:a-:b([^-/]+)-:c([^-/]+). If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length.

CVE-2026-4809 WRITEUP CRITICAL
Unsafe Client MIME Type Handling Can Enable Arbitrary File Upload in plank/laravel-mediable
plank/laravel-mediable through version 6.4.0 can allow upload of a dangerous file type when an application using the package accepts or prefers a client-supplied MIME type during file upload handling. In that configuration, a remote attacker can submit a file containing executable PHP code while declaring a benign image MIME type, resulting in arbitrary file upload. If the uploaded file is stored in a web-accessible and executable location, this may lead to remote code execution. At the time of publication, no patch was available and the vendor had not responded to coordinated disclosure attempts.
CVSS 9.8
CVE-2026-4861 WRITEUP HIGH
Wavlink WL-NU516U1 nas.cgi ftext stack-based overflow
A weakness has been identified in Wavlink WL-NU516U1 260227. This vulnerability affects the function ftext of the file /cgi-bin/nas.cgi. This manipulation of the argument Content-Length causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
CVSS 8.8
CVE-2026-4862 WRITEUP HIGH
UTT HiPER 1250GW Parameter formConfigDnsFilterGlobal strcpy buffer overflow
A security vulnerability has been detected in UTT HiPER 1250GW up to 3.2.7-210907-180535. This issue affects the function strcpy of the file /goform/formConfigDnsFilterGlobal of the component Parameter Handler. Such manipulation of the argument GroupName leads to buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.

CVE-2014-125112 WRITEUP CRITICAL
Plack::Middleware::Session::Cookie versions through 0.21 for Perl allows remote code execution
Plack::Middleware::Session::Cookie versions through 0.21 for Perl allows remote code execution. Plack::Middleware::Session::Cookie versions through 0.21 has a security vulnerability where it allows an attacker to execute arbitrary code on the server during deserialization of the cookie data, when there is no secret used to sign the cookie.
CVSS 9.8
CVE-2026-32748 WRITEUP HIGH
Squid has Denial of Service in ICP Response handling
Squid is a caching proxy for the Web. Prior to version 7.5, due to premature release of resource during expected lifetime and heap Use-After-Free bugs, Squid is vulnerable to Denial of Service when handling ICP traffic. This problem allows a remote attacker to perform a reliable and repeatable Denial of Service attack against the Squid service using ICP protocol. This attack is limited to Squid deployments that explicitly enable ICP support (i.e. configure non-zero `icp_port`). This problem _cannot_ be mitigated by denying ICP queries using `icp_access` rules. This bug is fixed in Squid version 7.5.
CVSS 7.5
CVE-2026-33285 WRITEUP HIGH
LiquidJS: memoryLimit Bypass through Negative Range Values Leads to Process Crash
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's `memoryLimit` security mechanism can be completely bypassed by using reverse range expressions (e.g., `(100000000..1)`), allowing an attacker to allocate unlimited memory. Combined with a string flattening operation (e.g., `replace` filter), this causes a V8 Fatal error that crashes the Node.js process, resulting in complete denial of service from a single HTTP request. Version 10.25.1 patches the issue.
CVSS 7.5
CVE-2026-33287 WRITEUP HIGH
LiquidJS has Exponential Memory Amplification through its replace_first Filter $& Pattern
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, the `replace_first` filter in LiquidJS uses JavaScript's `String.prototype.replace()` which interprets `$&` as a back reference to the matched substring. The filter only charges `memoryLimit` for the input string length, not the amplified output. An attacker can achieve exponential memory amplification (up to 625,000:1) while staying within the `memoryLimit` budget, leading to denial of service. Version 10.25.1 patches the issue.
CVSS 7.5
CVE-2026-33515 WRITEUP MEDIUM
Squid has issues in ICP message handling
Squid is a caching proxy for the Web. Prior to version 7.5, due to improper input validation, Squid is vulnerable to out of bounds read when handling ICP traffic. This problem allows a remote attacker to receive small amounts of memory potentially containing sensitive information when responding with errors to invalid ICP requests. This attack is limited to Squid deployments that explicitly enable ICP support (i.e. configure non-zero `icp_port`). This problem cannot be mitigated by denying ICP queries using `icp_access` rules. Version 7.5 contains a patch.
CVSS 6.5

This problem allows a remote attacker to perform a reliable and repeatable Denial of Service attack against the Squid service using ICP protocol. This attack is limited to Squid deployments that explicitly enable ICP support (i.e. configure non-zero `icp_port`). This problem _cannot_ be mitigated by denying ICP queries using `icp_access` rules. Version 7.5 contains a patch.

CVE-2026-27602 WRITEUP HIGH
Modoboa has an OS Command Injection
Modoboa is a mail hosting and management platform. Prior to version 2.7.1, `exec_cmd()` in `modoboa/lib/sysutils.py` always runs subprocess calls with `shell=True`. Since domain names flow directly into shell command strings without any sanitization, a Reseller or SuperAdmin can include shell metacharacters in a domain name to run arbitrary OS commands on the server. Version 2.7.1 patches the issue.

CVE-2026-29187 WRITEUP HIGH
OpenEMR Vulnerable to Authenticated Blind Boolean-Based SQL Injection in new_search_popup.php
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, a Blind SQL Injection vulnerability exists in the Patient Search functionality (/interface/new/new_search_popup.php). The vulnerability allows an authenticated attacker to execute arbitrary SQL commands by manipulating the HTTP parameter keys rather than the values. Version 8.0.0.3 contains a patch.
CVSS 8.1
CVE-2026-29785 WRITEUP HIGH
NATS Server panic via malicious compression on leafnode port
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.14 and 2.12.5, if the nats-server has the "leafnode" configuration enabled (not default), then anyone who can connect can crash the nats-server by triggering a panic. This happens pre-authentication and requires that compression be enabled (which it is, by default, when leafnodes are used). Versions 2.11.14 and 2.12.5 contain a fix. As a workaround, disable compression on the leafnode port.
