CVE-2026-72843: EverShop Missing Authorization on PATCH /api/customers/:id Allows Unauthenticated Account Takeover

The customer update route in EverShop is declared with "access": "public" in packages/evershop/src/modules/customer/api/updateCustomer/route.json, which causes the admin authentication middleware to call next() without checking the caller, and no customer-session middleware guards the route; the only middleware in the chain parses the JSON body. The handler in updateCustomer.js then loads the customer by the uuid taken from the URL path and writes the supplied fields back to that record, hashing a password if one is provided, without verifying that the caller owns the record. An unauthenticated request carrying a known customer uuid can therefore overwrite that customer's email address and password and read back the updated record from the 200 response, taking over the account and locking out its owner. Customer uuids are exposed through order confirmation email links and administrative URLs. Version 2.2.1 changes the route to "access": "private".

The The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.7.0. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode.

CVE-2026-91048: Apache Karaf: Missing authorization on the jdbc:* shell command scope allows privilege escalation to remote code execution via jdbc:ds-create

The jdbc shell command scope shipped no org.apache.karaf.command.acl.jdbc.cfg. Karaf's command guard (SecuredSessionFactoryImpl) treats a command with no matching ACL rule as allowed, so any authenticated shell session (including one holding only the viewer role) could run every jdbc:* command. jdbc:ds-create stores a fully attacker-controlled JDBC URL into a pax-jdbc-config factory Configuration with no validation. pax-jdbc-config reactively turns that into a live DataSource. Several JDBC drivers run code or SQL at connection time based on URL parameters (e.g. H2 INIT=RUNSCRIPT), so a viewer-level shell user could reach arbitrary code execution, bypassing the admin-role gate that already protects shell:exec. This is a privilege-escalation-to-RCE chain, not merely an "admin misconfiguration". The same applies to jms:* shell commands.

CVE-2026-91012: Apache Karaf: Path Traversal in Config Service Allows Manager-to-Admin Privilege Escalation

org.apache.karaf.config.core.impl.ConfigRepositoryImpl#update(pid, properties), which backs the "config" MBean and the config:* shell commands, derives the file it writes a configuration to from caller-supplied input without checking that the result stays inside ${karaf.etc}: * if the submitted property map contains a felix.fileinstall.filename entry, that value is turned directly into a File (getCfgFileFromProperty), so it can point to any absolute path the Karaf process can write to; * otherwise the configuration PID is concatenated verbatim into the target file name (generateConfigFilename(): new File(karaf.etc, pid + ".cfg")), so a PID containing ".." segments resolves outside ${karaf.etc}. createFactoryConfiguration() has the same issue via the factory PID/alias. Both code paths are reachable by any caller holding the "manager" role under Karaf's shipped command/JMX ACL (org.apache.karaf.command.acl.conf.cfg: "update = manager"). Such a user can therefore write attacker-controlled content to any file the Karaf process can write, including files the same ACL otherwise reserves to "admin" (etc/users.properties, etc/*.acl.*.cfg, etc/org.apache.karaf.management.cfg, and similar), allowing a manager-role user to grant themselves the admin role or otherwise take over the container. ConfigMBeanImpl.install() and the config:install shell command already guarded the equivalent risk on their own code path with a finalname.contains("..") string check, but that check does not stop absolute paths or symlink-based escapes, and it was never applied to ConfigRepositoryImpl.update() / createFactoryConfiguration() at all.
