+## v26.2.12
+
+### Jsonnet worker is fully isolated from the filesystem
+
+The hidden `jsonnet` subcommand that Kratos re-execs to evaluate Jsonnet mappers (OIDC claim mappers, courier templates,
+identity-schema transforms) now applies an empty [Landlock](https://docs.kernel.org/userspace-api/landlock.html) layer at startup.
+The worker only ever needs the inherited stdin/stdout/stderr — every path-based filesystem access from inside the worker is now
+denied by the kernel, even if a Jsonnet snippet were to bypass the in-process import barrier. Already-open file descriptors keep
+working, so the parent ↔ worker IPC is unaffected. This applies to Kratos OSS, Cloud, and OEL on Linux 5.13 and later, and is a
+no-op on other platforms.
+
+This is not configurable, for simplicity and security: there is no legitimate use case to allow the Jsonnet VM to read from disk.
+
+### Landlock filesystem sandbox for kratos serve (https://docs.kernel.org/userspace-api/landlock.html)
+
+#### Filesystem sandbox for kratos serve (OEL)
+
+Kratos OEL activates the [Landlock](https://docs.kernel.org/userspace-api/landlock.html) sandbox for the main `kratos serve`
+process after initialization. The process is then restricted to the files it needs at runtime:
+
+- `/dev/null` (subprocess plumbing)
+- `/etc/resolv.conf` and `/etc/hosts` (Go's pure-Go DNS resolver)
+- the running Kratos binary itself, with read+execute, so `jsonnetsecure` can re-exec it as a sandboxed worker
+- TLS certificates and keys for the public and admin listeners
+- the courier template directory (courier templates are loaded at runtime)
+- SMTP client certificate and key files (`courier.smtp.client_cert_path`, `courier.smtp.client_key_path`, and the equivalents
+  under `courier.channels[].smtp_config`)
+- **every file referenced from the config via a `file://` URI.** Kratos walks the loaded config once at startup and allows any
+  value that begins with `file://` — identity schemas, OIDC mapper templates, `web_hook` body templates, courier HTTP body
+  templates, session tokenizer mappers and JWKS files, and anything added to the config schema later. Operators do not need to
+  duplicate these paths under `security.landlock.allowed_paths`.
+- the directory containing the SQLite database — covers the database file itself and any `-journal` / `-wal` / `-shm` / transient
+  `-mj-XXXXX` siblings
+- in the case of SQLite: `/tmp`, `/var/tmp` and `/usr/tmp` since they are needed by SQLite.
+- any paths listed in `security.landlock.allowed_paths`
+
+The system trust store at `/etc/ssl` is **not** allowed. Operators who need to trust an additional CA must point `SSL_CERT_FILE` /
+`SSL_CERT_DIR` at the file and list it under `security.landlock.allowed_paths`. All other filesystem access is denied by the
+kernel after activation. This includes the `/proc` and `/sys` virtual filesystems.
+
+The sandbox degrades gracefully on older kernels and non-Linux platforms, so no action is required for deployments that don't
+support Landlock. To opt out completely (not recommended in production), set `security.landlock.disabled: true`.
+
+Configuration hot-reload still works as before with one caveat: Landlock restrictions are irrevocable for the lifetime of the OS
+process. Hot-reloading a config that flips `security.landlock.disabled` from `false` to `true` will not lift the sandbox — the
+process must be restarted for the change to take effect. Other config changes (allow list entries, courier templates, etc.) reload
+normally, but newly-introduced paths are only honoured on the next process start.
+
+#### Symlinks
+
+Symlinks in any configured path — `--config` files, TLS paths, `identity.schemas[].url`, the SQLite DSN,
+`security.landlock.allowed_paths`, and so on — are followed by the kernel when the rule is added at startup, so the rule attaches
+to the inode the symlink resolves to at that moment. As long as the target does not change, accesses through the symlink keep
+working transparently.
+
+Landlock rules are irrevocable for the lifetime of the process. If a symlink target swaps at runtime — for example when
+cert-manager or certbot renews a certificate by writing a new file and re-pointing the symlink — the rule still references the
+original target inode. Accesses through the symlink then resolve to the new inode, which is not in the allowlist, and the kernel
+denies them with `EPERM`. Restart `kratos serve` after any such swap so the rules attach to the new inodes.
+
+#### Troubleshooting
+
+A path that the sandbox does not allow surfaces in the application as `EPERM` ("Operation not permitted") on `open(2)` /
+`openat(2)` / `execve(2)` — Kratos typically logs it as `permission denied` while loading a config file, schema, template, or TLS
+material. To distinguish a Landlock denial from a regular Unix permission error, use the steps below.
+
+1. **Confirm the sandbox is the cause.** Check the Kratos startup logs for the line:
+
+   ```
+   level=info msg="Landlock filesystem sandbox is active."
+   ```
+
+   Just before it, two log lines list every path that was added to the allowlist:
+
+   ```
+   level=info msg="Landlock: collected roPaths." roPaths=[...]
+   level=info msg="Landlock: collected rwDirs." rwDirs=[...]
+   ```
+
+   If the path that triggered `EPERM` is missing from both lists, Landlock is the cause. As a sanity check, restart with
+   `security.landlock.disabled: true`: if the error disappears, the denial came from the sandbox.
+
+2. **Read the kernel audit log.** On Linux 6.10 and later, Landlock emits a kernel audit record for every denied access. The
+   record names the syscall, the resolved path, and the denied access right. Read it with one of:
+
+   ```bash
+   sudo journalctl -k --since "5 minutes ago" | grep -i landlock
+   sudo dmesg -T | grep -i landlock
+   sudo ausearch -m LANDLOCK_DENY -ts recent       # auditd-based distros
+   ```
+
+   A typical record looks like:
+
+   ```
+   audit: type=1334 audit(...): domain=2 op=fs blockers=fs.read_file path="/etc/kratos/schemas/fragments/address.json" dev="vda1" ino=131072
+   ```
+
+   The `path=` field is exactly what to add to `security.landlock.allowed_paths`. Older kernels (5.13 – 6.9) do not emit these
+   records — fall back to step 3 there.
+
+3. **Trace the syscall directly.** When the audit log is unavailable or the path is templated, attach `strace` to the running
+   process and watch for `EPERM` on the relevant syscalls:
+
+   ```bash
+   sudo strace -f -p "$(pgrep -f 'kratos serve')" -e trace=openat,execve -e status=failed
+   ```
+
+   Lines ending in `= -1 EPERM (Operation not permitted)` show the exact path the kernel rejected, even when Kratos's own log
+   message has been swallowed by a wrapper.
+
+4. **Fix the configuration.** Once the offending path is known, add it to the allowlist (a directory grants every file underneath;
+   a file grants only itself), then restart `kratos serve` — Landlock rules are immutable for the lifetime of the process, so a
+   hot reload will not lift the denial.
+
+   ```yaml
+   security:
+     landlock:
+       allowed_paths:
+         - /etc/kratos/schemas/fragments/address.json
+   ```
+
+### Normalize phone trait values to E.164 in webhook payloads
+
+When a phone trait is configured as a credential identifier (`code` strategy via `sms`), or as a recovery or verification address
+via `sms`, Kratos now rewrites the trait value to its E.164 form during validation.
+
+Previously, only the credential identifier and the recovery and verification address tables stored the normalized value, while the
+`traits` JSON kept the raw user input. Webhook payloads templated against `identity.traits.phone` therefore saw a different value
+than the one Kratos used internally as the identifier. The trait is now consistent with the canonical form, so webhook consumers
+and Kratos see the same phone number.
+
+Existing identities are not rewritten by this change. Use the `kratos cleanup normalize-phones` command to migrate stored
+identifiers; the trait values are corrected the next time the identity passes through validation (for example, on a settings or
+recovery flow that updates the trait).
