CVE-2025-49876

Before versions 1.7.4 and 2.0.0-beta.4, the Discord OAuth provider in FriendsOfFlarum does not check the 'verified' field for an OAuth email before passing it to Flarum core as trusted. This allows an unauthenticated attacker who knows a victim's email address to configure a Discord account with that unverified address and sign in as the victim without a password.

In Piwigo up to version 17.0.0beta1, when rating is enabled, an unauthenticated guest can call pwg.images.filteredSearch.create with a crafted ratings[] value and open the returned search URL. The value is not validated and is used as the upper bound in an SQL query, allowing extraction of database information or time delays.

In Piwigo before version 16.4.0, admin/themes_standard_pages.php validates uploaded logo content by MIME type but reuses the attacker-controlled extension in the filename. An authenticated administrator can upload a file with a server-executable extension, leading to code execution when placed in the logo directory.

In InvoicePlane before version 1.7.2-rc-1, the permitted template list is built by scanning a PHP template directory that can be written through an administrator-controlled file-write capability. A malicious PHP file placed in the directory is automatically trusted and can be selected as a public template, then executed when rendering a public invoice.

An unauthenticated calendar sender can place active markup in a COUNTER message's From address. Selecting the message in Zimbra Classic triggers stored XSS, allowing the attacker to access mailbox data and act as the victim.

When OnlyOffice/Document Editing is available, an unauthenticated remote attacker with access to an existing supported public Briefcase document can abuse unsigned save fields to perform path-traversal writes and execute commands as the zimbra user.

An unauthenticated sender can forge a share notification that triggers stored XSS when a signed-in Zimbra Modern recipient clicks Accept Share, allowing the attacker to access mailbox data and act as the victim.

An unauthenticated sender can forge a share notification that triggers stored XSS when a signed-in Zimbra Classic recipient clicks Accept Share, allowing the attacker to access mailbox data and act as the victim.

In the Linux kernel, in the RDMA/srpt driver, the function srpt_alloc_rw_ctxs() on partial failure does not reset the n_rw_ctx and n_rdma counters and does not clear the rw_ctxs pointer, leading to incorrect send queue credit accounting. The fix resets the counters and clears the pointer before returning an error.

In kitty from version 0.47.3 before 0.49.0, the colour control escape code handler does not neutralize field names in replies, allowing a program writing to the terminal to execute an arbitrary command in the user's shell. An attacker can compose a shell command using printable ASCII characters and a newline from handle_remote_ssh().
