Descripción técnica

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a remote content blocking bypass. rcube_washtml inspected the SVG SMIL animation attributes `to`, `from` and values for URIs, but not `by`; so markup such as in an HTML message caused remote content to be loaded without the user's consent, disclosing the client IP address and confirming that the message was opened. Upstream fixed this in the commit “Fix remote-content blocker bypass via SVG SMIL `by` attribute”.

———Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a remote content blocking bypass in the handling of FuncIRI attributes. rcube_washtml detected the CSS url() token with a pattern that enumerated only some of its escaped spellings, so values using other CSS escape sequences, for example \000075rl( or u\72 l(, were not recognized and remote content was loaded from an HTML message without the user's consent. Upstream fixed this in the commit “Fix remote content blocking bypass via CSS escapes in FuncIRI attributes (again)”, which resolves CSS escapes before matching and also inspects the `to`, `from` and `by` attributes.15h CVE-2026-1136057.2 ALT

——15Stirling-PDF from 2.13.2 through 3.2.0 contains an incomplete denylist in DatabaseService.validateSqlContent() that allows administrators to bypass H2 import restrictions using CREATE OR REPLACE ALIAS. Authenticated administrators can upload a crafted SQL backup to the import-database endpoint, where RUNSCRIPT defines H2 Java function aliases and restores Java-method execution.2d CVE-2026-1127777.2 ALT

——12Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a blocklist bypass in the Twig create() function because its class-name checks are case-sensitive while PHP class resolution is not. Attackers with template-execution rights, such as Control Panel administrators, can instantiate SplFileObject via a lowercase class name to read .env secrets or write a PHP file into the webroot for remote code execution.2d CVE-2026-77466—

——11Lychee is a free, open-source photo-management tool. Prior to 7.7.0, Lychee hides the Omnipay Dummy test provider from the checkout options in production through OmnipayFactory::get_supported_providers(), but CreateSessionRequest validates only that the submitted provider is an OmnipayProviderType and does not enforce OmnipayProviderType::isAllowed(). A buyer, including a guest when webshop_allow_guest_checkout is enabled, can submit Dummy directly and complete the test gateway flow without a real payment. When webshop_auto_fulfill_enabled is enabled, OrderCompletedListener::fullfillOrder() can then release the purchasable item. The issue requires access to the Supporter or Pro webshop and an enabled purchasable item. Testing bypassed the closed-source license middleware, so whether the real license layer performs additional payment-provider validation remains unverified. The payment finalize status check itself is not the root cause. This issue is fixed in version 7.7.0.7d CVE-2026-104024—

——1Incomplete List of Disallowed Inputs (CWE-184) in the dangerous-extension confirmation of the archive object viewer (peach.pas, grid_obj_open) in PeaZip 10.5.0 through 11.2.0 on Windows allows an attacker who convinces a victim to open an entry of a crafted archive to execute a program, or an arbitrary command, with no confirmation dialog. The prompt (Do you want to run this file?) is gated by SECEXTCONST, a hard-coded list of seven extensions (exe cmd msi bat ps1 vbs reg); the check is an exact string comparison of the entry extension against that list, so it answers only whether the extension is one of the seven and never whether the shell will execute the file. Shell-executable and scripting-host types that Windows runs through ShellExecuteW are absent from the list, among them .url and .lnk. An archived Windows Internet Shortcut (.url) whose URL line is attacker-controlled is launched with no prompt, while the byte-identical content in an entry named .bat does raise the warning in the same session. A .lnk entry raises the ceiling from launching a program to running a command line, because a Windows shortcut carries arguments: a proof-of-concept shortcut targeting cmd.exe with an attacker-chosen command line executed with no prompt. The shortcut target is not confined to the local disk; the shell also resolved an attacker-named UNC path (fetching a remote payload was only attempted, not demonstrated). No privilege escalation; everything runs as the user who opened the archive.6d CVE-2026-1020876.5 MED

——5An Incomplete List of Disallowed Inputs vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When in a BGP traffic engineering scenario a specific, valid, optional, non-transitive BGP update is received over an established BGP session, RPD crashes and automatically restarts, which leads to traffic impact until routing has reconverged. This issue affects: Junos OS: * All versions before 23.2R2-S6; * 23.4 versions before 23.4R2-S7; * 24.2 versions before 24.2R2-S4; * 24.4 versions before 24.4R2-S4; * 25.2 versions before 25.2R1-S2, 25.2R2; Junos OS Evolved: * All versions before 23.2R2-S6-EVO; * 23.4 versions before 23.4R2-S8.11-EVO; * 24.2 versions before 24.2R2-S4-EVO; * 24.4 versions before 24.4R2-S5-EVO; * 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO;7d
